Preface to the Series

The RIKEN BNL Research Center (RBRC) was established in April 1997 a t Brookhaven National Laboratory. I t is funded by the "Rikagaku Kenkyusho" (RIKEN, The Institute of Physical and Chemical Research) of Japan. The Center is dedicated to the study of strong interactions, including spin physics, lattice QCD, and RHIC physics through the nurturing of a new generation of young physicists.

The RBRC has both a theory and experimental component. At present the theoretical group has 4 Fellows and 3 Research Associates as well as 11 RHIC PhysicsRJniversity Fellows (academic year 2003-2004). To date there a re approximately 30 graduates from the program of which 13 have attained tenure positions at major institutions worldwide. The experimental group is smaller and has 2 Fellows and 3 RHIC PhysicsKJniversity Fellows and 3 Research Associates, and historically 6 individuals have attained permanent positions.

Beginning in 2001 a new RIKEN Spin Program (RSP) category was implemented at RBRC. These appointments are joint positions of RBRC and RIKEN and include the following positions in theory and experiment: RSP Researchers, RSP Research Associates, and Young Researchers, who a r e mentored by senior RBRC Scientists, A number of RIKEN Jr. Research Associates and Visiting Scientists also contribute to the physics program a t the Center.

- RBRC has a n active workshop program on strong interaction physics

with each workshop focused on a specific physics problem. Each workshop speaker is encouraged to select a few of the most important transparencies from his or her presentation, accompanied by a page of explanation. This material is collected a t the end of the workshop by the organizer to form proceedings, which can therefore be available within a short time. To date there are sixty- eight proceeding volumes available.

The construction of a 0.6 teraflops parallel processor, dedicated to lattice QCD, begun at the Center on February 19, 1998, was completed on August 28, 1998 and is still operational. A 10 teraflops QCDOC computer in under construction and expected to be completed this year.

November 16-17,2004 Brookhaven National Laboratory, Upton, NY 11973

The seventh evaluation of the RIKEN BNL Research Center (RBRC) took place on November 16 and 17, 2004, at Brookhaven National Laboratory. The present members of the Scientific Review Committee are Dr. Jean-Paul Blaizot, Professor Makoto Kobayashi, Dr. Akira Masaike, Professor Charles Young Prescott (Chair), Professor Stephen Sharpe (absent), and Professor Jack Sandweiss. We are grateful to Professor Claudio Rebbi who filled in for Professor Sharpe. In order to illustrate the breadth and scope of the program, each member of the Center made a presentation on his research efforts. In addition, a special presentation was given jointly by our collaborators, Professors Norman Christ and Robert Mawhinney of Columbia University, on the progress and status of the RBRC QCDSP/QCDOC Supercomputer program. Although the main purpose of this review is a report to RIKEN Management (Dr. Ryoji Noyori, RIKEN President) on the health, scientific value, management and future prospects of the Center, the RBRC management felt that a compendium of the scientific presentations are of sufficient quality and interest that they warrant a wider distribution. Therefore we have made this compilation and present it to the community for its information and enlightenment.

Thanks to Brookhaven National Laboratory and to the U. S. Department of Energy for providing the facilities to hold this meeting.

ODerator Mixinq and BK ...

First order chiral perturbation theory predicts that

and, unfortunately, that

so ... as the chiral limit is approached the wrong chirality operators will dom in ate.

F 0 Don't work in in chiral limit : For the range of masses we are working a t quenched results suggest that the matrix elements of the wrong chirality operators can be as much as 50-100 times larger than the operator.

W

Domain Wall fermions have exact flavour symmetry, but do break chiral symmetry. A simple theoretical analysis shows that mixing with these wrong chirality operators is suppressed by a factor of

( a m r e s I 2 - and may be ignored.

- This is the great advantage of DWF .

3

To calculate

BK on the lattice

we need to construct ______ correlation functions - for -interpolating operators for the ICo and KO and QV~J+AA , with the Ko a t large negative time and the K O a t large positive time.

- For our calculation me fix the KQ operator a t t = 4 and the KQ operator a t L === 28 . We then calculate the above ratio for all operator times.

For each sea mass, we calculate this for many combinations of valence quark mass, both degenerate and non-degenerate.

Conclusions.. . Future

We have included both dynamical quarks (partially) and the effects of non-degenerate masses (mu = rn(1 $= 7 n S ) into the calculation of UI,- on the lattice. Both these effects lead t o a lower value for BK. Our final value is

U K ( ~ , 2GeV) = 0.496( 17)

This is statistical error only as:

1. Study performed a t a single lattice spacing

2. with only 2 dynamical flavours of quark

3. a t relatively heavy dynamical quark masses

4. in a finite volume

5. with a relatively small time extent for the lattice

Lattice Calculation of the Neutron Electric Dipole Moment

Abstract : We present preliminary results for nucleon dipole moments computed with domain wall fermions. Our main target is the electric dipole moment of the neutron arising from the 6 term in the gauge part of the QCD lagrangian. The calculated magnetic dipole moments of the proton and neutron are in rough accord with experimental values.

Weak interactions: CKM mechanism: d N < - 10-30e-cm (vanishes a t one-loop), many orders of magnitude below the experimental bound [l], 12~1 < 6.3 x 10-26e-cm.

Experimental bound + model calculations imply 6 5 which is unnaturally small. However, no known symmetry to say it vanishes. This is often called the Strong CP problem.

P * v1 To translate the above experimental bound to a constraint on the

fundamental 6 parameter requires evaluation of nucleon matrix elements.

Lattice method is first-principles technique for calculation.

There have been several past attempts t o calculate d ~ , in the continuum and on the lattice.

1. V. Baluni [2] computed d~ in the framework of the MIT bag model obtaining d~ N 8.2 10-168e cm

2. Crewther et a/. [3], using an effective chiral lagrangian found d~ oc 8 M: ln(M2) N 5.2 10-168e-cm

3. Pospelov and Ritz [4], using QCD sum rules techniques, found d N = 1.2 x 10-168e-cm

4. Aoki and Gocksch [5] were the first t o try a pioneering lattice QCD calculation o f d~ (quenched approximation).

Corn putational strategy Two important elements:

C'L c. Ratios of GM(q2) and F3(q2) wi th G E ( ~ ~ ) , limit q2 -+ 0, yield magnetic and electric dipole moments, respectively:

(2) Expand ( p ' , s l P I p , s ) ~ t o lowest order in 8 and compute F3(q2) in each topological sector V , and then average over all sectors with weight Qv.

" Disadvantage (unlike the backg round-electric-field-method [8] used in [5]): our method does not allow a direct calculation a t q2 = 0.

G 0

On a finite lattice only the form factor F1 can be computed a t q2 = 0 [9]. Our method requires extrapolation of the form factors t o q2 = 0 from non-vanishing values of q2.

Lattice: 163 x 32, Ls = 12, and the inverse lattice spacing in the m s e a - - 0 limit is a-l = 1.7 GeV.

We have averaged over time slices 14-17 and (equivalent) per- mutations of the momenta p’= (1,0,0), (l,l,O), and (l,l,l).

Topological charge:

Q was computed by integrating the topological charge density after APE smearing the gauge fields (20 sweeps with ape weight 0.45) [ll]. I

We are also investigating computing the topological charge from the index defined from the domain wall fermion Dirac operator (strictly valid in the limit Ls -+ 00).

Outlook In the near future, we will strive t o reduce the statistical error on our determination of d~ which has already yielded an interesting first-principles bound on the magnitude of d ~ .

G: 00

I Do this by measuring d~ on all available N f = 2 lattices (N 1000/msea) and measuring more than once on each lattice.

We have begun new calculations with smeared sources.

Compute the m s e a dependence as well.

1. Intrdduction Motivation

Understanding of hadron dynamics based on (lattice) QCD Strict test of Standard model requires comparison of theory and experiment. But one of main theoretical uncertainties is hadronic effect. To calculate hadron scattering (XX scattering) based on QCD, nonperturbative method, e.g. lattice QCD, is required.

e 'Dynamical' physical quantity beyond hadron mass z m Isospin I = 2 S-wave xx scattering phase shift a&)

Most of the lattice studies have focused on 'static' physical quantities, e.g. hadron spectrum.

Previous lattice calculation of I = 2 TT scattering phase shift Only pioneering studies have been reported.

Fiebig, Rabitsch, Markum, and Mihaly, 2000 TT potential CP-PACS Collaboration, 2002 finite volume method in center of mass system Kim, 2003 finite volume method with anti-periodic boundary condition

They employed quenched approximation (neglect effect of quark pair production and annhilation), and did not take the continuum limit.

2. three different lattice spacings

3. center of mass (CM) and two laboratory (L1 and L2)

I

Ginzburg-Landau approach helps us examine effects of nonzero strange quark mass and charge neutrality on the melting pattern of diquark condensates in weak coupling.

First rigorous weak coupling calculations of the pairing gap in the presence of nonzero strange quark mass.

Effects of the thermally fluctuating color magnetic fields on the melting pattern can change the phase structure.

1 Lmulication on the NuTeV anomalv 1 Based on a NLO calculation of the P-W ratio (see "standard" part of the talk), using the new CTEQ PDFs:

A value of IS-) = 0,001 7 (central value) can reduce the NuTeV anomaly from a -3 o effect to -1.5 6; a value of [S-] - 0.003 - 6.003 would then reduce it to within 1 6. The actual effect on the NuTeV measurement must await reanalysis by the experimental group, correcting current flaws, extending to NLO, as well as taking into account global constraints. The variation of (S-] underestimates the full uncertainties (isospin, higher mist, . . .). Again, a definitive answer will have to come from NuTeV.

The houndv ofcurrenr uncwtaing studies suggest thur rhr dimuon datu, the Weinberg angle measurement and other globul obtu sets used in QCD parron structure analysis can all be consistent with the SM.

Status (theory) of the NuTeV anomaly @The cross section r a t i o s W - that are closely related t o the NuTeV extraction of the Weinberg angle have been thoroughly reevaluated by many authors under several SM corrections:

@ pQCD corrections (NLO & masses)

B electroweak corrections

@ nucleon parton structure effects & uncertainties

@ The exact impact of the corrections on the extraction of sin2 8, cannot be quantified in theory because of the involved Monte Carlo / detector ef fects in modeling "long" and "short" events in the NuTeV experiment. The closely related theoretical observables receive corrections that are o f the order of the assigned experimental errors o r bigger. Partonic uncertainties (strangeness asymmetry, ...) do even survive in the ideal Paschos-Wolfenstein ratio.

@ These effects have, so far, not been assigned a systematic error in the NuTeV value of sin2 8,. Claims that they cancel in the NuTeV (LO Monte Carlo) analysis procedure are a posteriori and have not been substantiated by an analysis that takes them into account ab initio. Before a careful re-assessment of all theoretical uncertainties (pQCD ct non-pQCD & electroweak) the 3 o discrepancy with the SM cannot be taken at face value.

e All large machines are running reliably at 420 MHz.

e Operation at 450 MHz may be possible but our present emphasis is on bringing up the large machines.

e The high-speed communications has given little trouble. (This may change at 450 MHz!)

e After much effort the DDR memory is working very reliably.

e Ethernet has been the biggest problem. --- Tricky reset sequence required at power-up.

-. At 420 MHz, Ethernet link is sometimes lost.

- Communication can be re-established by resetting a portion of the Ethernet hardware.

1.- Now automatically reset when a lost link is de- tected.

Outlook

e Calculation of A I = 3 / 2 amplitudes is practical with an on-shell T-T final state.

e Calculation of AI = 1/2 amplitudes is possible using G-parity boundary conditions. I = Quenched calculations are not possible ’because

zero-momentum, q’-q‘ states will dominate.

2 . Charge conjugation of the gauge fields on the boundary requires special configurations.

3. Decay to the vacuum is allowed and must be subtracted.

e Using a K-meson with 0 (Rummukainen- Gottlieb) would address 2. and 3. above.

350

CONCLUSION

0 QCDOC computer construction is nearly complete.

Design goal of $l/Mflops has been achieved (see Bob’s discussion of QCDOC software next).

- Initial RIKEN support has driven this project with international benefits for:

UKQCD, US/SciDAC.

QCDOC has also had a broader impact: BlueGene/L IBM machine.

0 As Bob will discuss, this will enable RBRC theorists to continue outstanding research using lattice QCD:

Nucleon structure.

K meson decay, including CP violation.

Electromagnetic properties of hadrons.

Properties of the quark-gluon plasma and RHIC physics.

Invention and development of new methods.

Research Summary

Since 4 and 6 in the above publication list are related to RBRC, I will summarize researches contained in these papers.

In the paper entitled “Perturbative determination of mass dependent renormalization and improvement coefficients for the heavy-light vector and axial-vector currents with relativistic heavy and domain-wall light quarks,” I, in the collaboration with N. Yamada (RBRC) and Y. Kurmashi (Tsukuba), have determined the mass dependent renormalization coefficients for the heavy-light vector and axial vector currents consisting of the relativistic heavy and the

. domain-wall light quarks. We have carried out perturbative calculation at the one loop level to remove the systematic error of O(a, am^)" a p) as well as O(a, am^)') (n >O), where p is a typical momentum scale in the heavy-light system. We have pointed out that using a lattice chiral fermion for the light component of the heavy-light currents brings an advantage to the heavy-light physics because it leads to exact .relations between the renormalization coefficients of the vector and axial vector currents. We have presented the results obtained with three different gauge actions as a function of heavy quark mass and domain-wall height.

In the paper entitled “Twisted-mass QCD, O(a) improvement and Wilson chiral perturbation theory,” I, in collaboration with 0. Baer (Tsukuba), have pointed out a caveat in the proof for automatic O(a) improvement in twisted mass lattice QCD at maximal twist angle. With the defkition for the twist angle previously given by Frezzotti and Rossi, automatic O(a) improvement can fail unless the quark mass satisfies m(l >>a2A3 QCD. We have proposed a different definition for the twist angle which does not require a restriction on the quark mass for automatic O(a) improvement. In order to illustrate explicitly automatic O(a) improvement we have computed the pion mass in the corresponding chiral effective theory. We have considered different definitions for maximal twist and shown explicitly the absence or presence of the leading O(a) effect, depending on the size of the quark mass.

Pion electromagnetic form factor with quenched domain wall f e r m i o n s The pion electromagnetic (EM) form factor is one of the simplest quantities in QCD.

Some new experiments on this quantity at relatively large momentum transfers are under way[l]. I have calculated the pion EM form factor in the quenched lattice QCD using domain wall fermions (DWF) with several momentum transfers which partially cover the above experiments. The DW’F enables us to access lighter quark masses than ever, because it has good chiral properties which are quite important for the Nambu-Goldstone bosons such as the pion. This work is in collaboration with the RBC-collaboration.

I calculated the form factor with small momentum transfers last year[2]. In th i s year I have calculated it with larger momenta to obtain the data near the experimental values at J-Lab.

Firstly I summarize the lattice parameters. We employ the DWF action for the quark action. The number of sites in the fifth direction is L, = 12 and the domain wall height M5 = 1.8. Quark masses are taken to be mga =0.08, 0.06, 0.04, 0.03 and 0.02 whose pion masses in the physical unit are approximately 760, 660, 540. 470 and 390 MeV, respectively. The gauge action is a renormalization-groupimproved gauge action called DBW2 with the lattice size 163 x 32. The gauge coupling is taken to be 3 = 0.87, which gives the lattice spacing u-’ N 1.3 GelJ and a sufficient spatial lattice volume I’ = (2.4fm)3 for a pion. The number of configurations is 100. The explicit chiral symmetry breaking due to the finiteness of the fifth direction L, is characterized by the residual mass mres. Our result of nz,, after the chiral extrapolation is about 1.5 Ale\.’. which is much smaller than the quark masses mf.

The pion EM form factor F,(Q’) is defined by F,(Q2)(pp + p L ) = (7r4(p)~jp17r+(p’)). where q2 = -Q2 = ( p - p’)’ and j , is the EM current. We note F,(O) is the electric charge of a pion and we employ this relation as a numerical check. The past calculated momentum transfers of the form factor are ~ 7 = (O ,O, 0), (1,0,0) and (1.1.0) in the uni t of 27rlLa with the spatial lattice size L. They correspond to physical values of Q2 = 0. 0.26, and 0.53 Gel”, respectively. On the other hand. the momenta in the new calculation are &’ = 0.53 and Q2 = 1.03 Gel-’. To improve the statistical errors. we have changed the calculation method and the former nionientum (Q’ = 0.53) has been calculated again.

The EM current used here is the local current which is not conserved on the lattice and requires operator renormalization before comparing with the matrix element in the

continuum, We have calculated the renormalization factor of the axial vector current, ZA, nonperturbatively using lattice QCD. Z A is equal to the vector current factor 2,. in DWF and its chiral-extrapolated value is ZA = 0.7798(5).

All the fitted results of the pion EM form factor after the renormalization are sum- marized in Table 1. We see excellent agreement with unity for Q2 = 0 for the numerical check. Quark mass dependence of the form factors with the finite momenta seems to be rather small, although they have relatively large statistical errors.

mfa Q2 = 0 Q2 = 0.26 Q2 = 0.53 (old) Q2 = 0.53 (new) 0.08 1.003(19) 0.783(24) 0.603(48) 0.621(30) 0.06 l.OlO(22) 0.779(31) 0.583(73) 0.597(38) 0.04 1.013(27) 0.761(44) 0.564(138) 0.550(54) 0.02 1.011(34) 0.689(77) n/a 0.473(71)

Q2 = 1.06 0.458(18) 0.449 (25) 0.442(42) 0.421(61)

The present results show a rather small quark mass dependence. The chiral extrapolated values are consistent with the vector meson dominance, i.e., a monopole function 1/(1 + Q2/m;4), other recent lattice studies and the experimental values. This might indicate that the pion EM form factor is not sensitive to some systematic errors such as quenching effects and explicit chiral symmetry breaking due to the finite quark masses. The paper on these results is now in preparation.

Calculation of kaon matrix elements in quenched domain-wall QCD

Jun-Ichi Noaki for the RBC Collabolation

1 Introduction Non-perturbative treatment of kaon decay processes by the numerical simulation of lattice QCD has been an in- dispensable part for further understanding of the Standard Model. In the quantities related to kaon physics such as f,, f ~ , BK, ReAo/ReAz and € ' / e , the first three are constructed straightforwardly on the lattice. However, in actual numerical simulations, there are several potential sources of systematic error, namely explicit breaking of chiral symmetry, scaling violation, finite volume effect and quenching effect. We present calculations of the decay constants and kaon B-parameter BK as the first stage of RBC Collaboration's longstanding quenched numerical simulations using DBW2 gauge action and domain-wall fermions. Due to this combination of the lattice action, we have chiral symmetry to a good approximation [I]. Our numerical simulation are carried out on two kinds of gauge ensembles with the lattice scale a-' = 2 GeV and 3 GeV in a similar physical size of box of x (1.6fm)3. It allows 11s to examine the scale dependences of our results. To make up physical quantities from our lattice results. we computed the renormalization factor non-perturbatively [2], which is another characteristic of our calculation.

2 Decay constants of light mesons From the results of the fit of correlation functions ( P - P wall-wall and A4 - P ) , we construct the decay constant on the lattice fps. By the interpolation to the point mps = m~ and the linear extrapolation to mps = m,, we obtain the lattice values of f~ and fn, respectively. Physical values of these decay constants are computed by multiplying the renormalization factor ZA, which is extracted from the ratio of the conserved axial current and the conventional current on the lattice. The left panel of Figure 1 shows the scaling property of f K / fir, where our results are indicated by filled circle (a-' zs 3 GeV) and filled square (2 GeV). With the result of previous work of the RBC collaboration using DBW2 gauge action [I], which is indicated by the triangle, we take continuum limit using the linear function. The result fK/ fn = 1.098(13) is reasonably consistent with the estimation by the quenched chiral perturbation theory [3]. In the right panel of Figure 1, a similar plot for fT (filled symbols) and f~ (open symbols) are shown. Compared with the experimental results, our results of fir is larger by zs 7% and . f ~ is RZ 4% smaller, in the continuum limit.

3 Kaon B-parameter In Figure 2, we plot our lattice results of BK with the two kinds of fit curve

Both functions fit our data with a reasonable value of X2/dof. In particular for u-' M 2 GeV, result of 52/50 is consistent with the value of -& within the error, which means our data reproduced the expectation by the quenched chiral perturbation theory [4],

In the next step, we calculated renormalization factor Z B ~ = Zo,,,,/Z~. Though the parity conserving part of the local operator has the chiral structure of VV + AA, another chirality VV - AA, SS f PP and

.TT may contribute to the renormalized value due to the small but &lite breaking of the chiral symmetry: O$y;iAA = E, ZVV+AA;~O,: where x denotes the possible c h i d structures. In order to estimate the degree of this operator mixing, we calculated all coefficients ZVV+AA;~ and B-parameters of 0, for u-l M 2 GeV lattice. Figure 3 shows the results of the leading coefficient ZVV+AA;VI/+AA as a function of the renormahation scale squared, p&. In contrast, as seen in Figure 4, ZVV+AA;VV-AA is negligiblly small. In particular, after the chiral extrapolation for eachp?!,,,: they are consistent with zero. Since there is a complicated issue called "mass- pole" for other operator, we carried out our estimation at the largest quark mass imd largest pyait to avoid any underestimation. As a result of the combination of these coefficients and B-parameters of relevant operators shown in Figure 5, we confirmed that the mixing of operators with the wrong chirality can be negligible. Its degree is less than the statistical error of the leading term ZVV+AA;VV+AA~VV+AA. This demonstration is actually predicted by the notion of the fact that the exchange of two chiral modes is an (me,) effect in the domain-wall fermion formalism. Since it takes two exchanges for the operator mixing to occur, this is the O(m?-) effect.

After the procedure which convert our renormalization factor to one in the MS scheme, we reached to our h a l results of BK at p = 2 GeV. In Figure 6, we summarize our results (filled symbols) and previous results of the RBC [5] using Wilson gauge action and of the CP-PACS Collaboration [6] using Iwasaki gauge action. While there is a distribution between calculations performed with a similar parameter set at a-' M 2 GeV, our result and the CP-PACS result agree within the statistical error for the h e r lattice u-' M 3 GeV. By extrapolating our two data points linearly, we obtained B ~ m , p = 2 GeV] = 0.569(21).

U. van Kolck’s Research

2003/04

Since the 2003 RBRC review meeting, my research activities involved various aspects of nuclear effective field theories (EFTS). Focus was on reactions involving few-body systems - Compton scattering and pion production- and symmetries --chargesymmetry breaking and parity violation.

1 Low-energy Compton scattering

The electromagnetic polarizabilities are a fundamental property of any composite object. For example, in a simple quark-model picture the polarizabilities contain averaged information about the charge and current distribution produced by the quarks inside the nucleon. Photon tagging can be used to measure Compton scattering on weakly-bound systems, since it facilitates the separation of elastic and inelastic cross sections. Proton electric and magnetic polarizabilities, ap and &,, can be obtained from elastic scattering on hydrogen targets. In contrast, the absence of free neutron targets requires that the neutron polarizabilities an and /?, be extracted from scattering on deuterium targets. Data exist for coherent yd + yd from 49 to 95 MeV, and for quasi-free yd + ypn from 200 to 400 MeV. The coherent process is particularly sensitive to the isoscalar combination of polarizabilities, a~ = (ap + an)/2 and ijrhi = (& + p n ) / 2 , via interference with the larger Thompson term. The extraction of neutron polarizabilities from these data requires a consistent theoretical framework to separate nucleon properties from nuclear effects. In the long-wavelength limit of interest such a framework is EFT.

The amplitude for Compton scattering on the nucleon has been computed to 0 (Q4) by J. McGovern. To this order, the only undetermined parameters are the short-range contributions to the polarizabilities. We have calculated the amplitude for coherent Compton scattering on the deuteron to the same order in Weinberg’s power counting ’. The single-nucleon amplitude is boosted to the relevant deuteron frame, and all two-nucleon diagrams up to 0(Q4) are added. The kernel for Compton scattering on the deuteron is the sum of the singlenucleon amplitude and two-nucleon contributions. The full amplitude is obtained by sandwiching the kernel between deuteron wavefunctions obtained within EFT to the appropriate order. There are no unknown parameters in the two-nucleon sector.

We have now fitted the world’s low-energy proton and coherent deuteron data, and extracted < 200 MeV), we both the proton a i d neutron polarizabilities ’. From the proton data (w!

aN = (13.0 f ~.g)?;:; x 1 0 - ~ fm3,

PN = (-1.8 z t I.S>?X:; x 1 0 - ~ fm3. (2)

This is the first time such a consistent extraction is done. Our values for the proton are close to existing model-dependent analyses that include higher-energy data, but with considerably larger error bars that result from our restriction to low energies. Neutron polarizabilities are comparable to proton values within (rather large) errors.

2 Charge-symmetry breaking in pion production

The observed nucleon mass splitting has far-reaching consequences in nucleosynthesis, but it is not well understood. It originates from both electromagnetic and quark-mass-difference effects. An empirical determination of the latter component of the nucleon mass difference could allow, together with its calculation in lattice QCD, for an extraction of the down-up mass difference. While electromagnetic interactions break isospin in general, the quark mass difference breaks explicitly charge symmetry, a particular isospin rotation that interchanges up and down quarks. W i t h the framework of the EFT with explicit pion fields, additional experimental information on the relative size of the two mechanisms comes from associated s-wave pion-nucleon interactions required by chiral symmetry. Lacking accurate low-energy pion-nucleon scattering data, we turn to reactions where a TO is emitted near threshold after being created by one nucleon and rescattered by a second. Recent results of the TRIUMF np + d?ro 'experiment have confirmed the prediction of Miller, Niskanen and van Kolck that the two contributions to the nucleon mass difference can produce -via pion rescattering- a relatively large contribution to the front-back asymmetry, of opposite sign to more conventional mechanisms. Unfortunately, the interference with the largest of these standard mechanisms, pi-eta mixing, makes the h a l result also sensitive to the poorly-known eta-nucleon coupling and pi-eta mixing angle.

We have argued that more experimental information is needed to separate these various charge-symmetry breaking (CSB) mechanisms. With our theoretical support, an IUCF collaboration led by A. Bacher and E. Stephenson has recently reported the first unambiguous observation of the CSB reaction dd + mo near threshold. The measured cross section depends on the same CSB mechanisms as does the np + d71-O asymmetry, but with different weights. It is proportional to the square of the CSB pion production amplitude, but the interpretation of the experimental result is complicated by the rich isospin-conserving interactions among the four nucleons. In order to tackle this issue, we have assembled a theoretical collaboration, which has by now identifled the leadiig CSB operators in EFT and evaluated the main treelevel mechanisms near threshold, using a simplied set of d and a wave functions and a plane-wave approximation for the dd initial state 2. The leading-order term stemming from the nucleon-mass contributions is shown to be suppressed because of poor overlap of initial and hal states, while the

398

higher-order pi-eta-mixing and heavy-meson-exchange amplitudes contribute coherently to the cross section. Our preliminary results suggest that the largest contribution comes from pi-eta mixing, and is of the same order of magnitude as the measured cross section. Incorporation of a realistic a wave function and dd interactions is in progress.

3 Charge-symmetry breaking in the N N potential

Given their importance in pion production it is natural to wonder what role the s-wave pion- nucleon CSB interactions associated with the nucleon mass difference play in other nuclear CSB observables. They contribute, for example, to the two-pion-exchange CSB N N potential.

We have shown that the effects of the nucleon mass difference on the nuclear potential can he obtained easily after a field redefinition in the EFT involving nucleons and pions. This field redefinition eliminates the nucleon mass difference from external states in favor of new isospin- violating interactions. As an example, we rederived previously-obtained results on the CSB class-I11 potential -which splits two-neutron and two pron interactions- including its two- pion exchange component. We also derived the remaining component of the CSB N N potential, the class-rV force, which breaks charge symmetry by mixing I = 0 and I = 1 channels. We have found that in the EFT the leading class-IV force comes from the same one-pion exchange already established in the literature.

We then used this field redefinition to derive the leading-order three-nucleon force that violates isospin -an in particular c h a r g e symmetry *. The effect of the this three-nucleon force was investigated in the trinucleon systems using Faddeev calculations. We found that the contribution of this force to the 3He - 3H binding-energy difference is given by AEFiF cz 5 keV.

4 Parity violation in the N N potential

Renewed interest exists in hadronic parity violation (PV), as current experiments do not seem consistent with the conventional parametrization in terms of one-boson-exchange models, PV electron scattering on the proton and deuteron marginally fits with existing theory. and new measurements are underway. Various PV observables have been analyzed within EFT, hut there has been no systematic study of PV nuclear forces win this context.

For some time we have been reexamining the PV N N force in light of EFT. We have now built the complete EFT framework for the analysis of PV utilizing Weinberg's formulation. We organize the PV N N interaction in powers of derivatives and inverse powers of gauge- boson masses, truncating the discussion at O(Q) and lowest order in the Fermi coupling. The lowest-order interaction, from one-pion exchange, occurs at O(Q-'). At O(Q) there exist five

399

contact interactions together with a mid-range component arising from two-pion exchange. We compare this description to the conventional parametrization, and discuss how the short-range parameters can in principle be determined empirically from existing and future experiments. We h d that the novel two-pion-exchange potential is signiscant when compared to one-heavier- boson exchange in the same channels, and might therefore affect the fits to observables.

5 Coupled-channel scattering

In certain situations crow sections are much larger than the size set by the range of the interactions. One example is N N scattering near threshold, for which an EFT without pion fields has been constructed. In general, more than one channel might be involved, and one or more could be ‘Lopen”,in the sense of a sink’of flux, as for annihilation channels in low-energy proton- antiproton scattering. Open channels are usually described using optical potentials. What is the EFT counterpart?

We have developed an EFT for coupled-channel scattering with short-range forces that can be used when the cross sections in two or more channels are much larger than the interaction range. We showed how one can obtain a cutoff independent 2‘-matrix starting with the EFT Lagrangian with contact interactions. We have obtained a low-energy expansion of the coupled- channel 2’-matrix analogous to the effective-range expansion in the w e of a single-channel elastic scattering. We have shown also how one recovers the well-known analytic structure ---cusps and steps- of the coupled-channel 2’-matrix. In the case of an open channel, the 2’-matrix can be expanded in powers of the ratio of the energy above threshold to the threshold energy. As a result one obtains an effective-range-like expansion with complex parameters, which is analogous to what one derives using optical potentials.

Research Summary - Tilo Wettig

In the past year my work has been focused on the following topics.

1. Matrix models and lattice simulations for QCD at nonzero chemical potential Together with Gernot Akemann, I have performed lattice simulations to test predictions of random matrix models for the eigenvalue spectrum of the lattice Dirac operator at nonzero chemical potential. Excellent agreement was found, and the results were published in Phys. Rev. Lett. [l]. This was the first lattice study of this kind. In the meantime, I have refined the analysis and have thereby been able to rule out one of two competing models on the basis of the lattice data. More detailed inves- tigations are underway, and the results, whch are of interest for studies of the QCD phase diagram, will be published soon.

2. Color-flavor transformation My graduate student Yi Wei and I have derived two new versions of the color-flavor transformation for gauge group SU(N): (a) a version for bosonic fields and (b) a supersymmetric version for fields that can contain both bosonic and fermionic components. This work generalizes an earlier result for fermionic fields computed by my former postdoc Boris Schlittgen and myself. The new results can be applied to the theory of boson-induced Yang-Mills theory with or without physical fermions as recently suggested by Budczies and Zirnbauer. In the process of deriving the transformation we have also computed several new results for integrals over non-compact groups. We are currently writing two papers for publication in Nucl. Phys. B.

3. Small eigenvalues in the Gaussian Unitary Ensemble of Random Matrix Theory In the Gaussian Unitary Ensemble of Random Matrix Theory, there is nothing special about the point X = 0 in the eigenvalue spectrum. However, this point can be made special by looking at the absolute values (or the squares) of the eigenvalues. I have computed the distributions of individual small eigenvalues for this case. These are of interest for lattice simulations with Wilson and overlap fermions. A paper for publication in Phys. Rev. E is nearly completed.

405

4. Normal modes of chiral random matrix ensembles In the framework of Random Matrix Theory, analytical predictions have recently been made for the behavior of normal modes, i.e. for the fluctuations of the eigenvalues about their average locations. Together with Wolfgang Soldner, I have performed lattice simulations to test these predictions. The lattice data agree with the predictions up to a characteristic scale which can be understood theoretically from the low-energy effective chiral theory. Our results are currently being written up for publication.

5. Benchmarking of supercomputers for lattice QCD I was a member of a benchmarking committee at DESY to evaluate various supercomputing platforms with regard to their suitability for lattice QCD. These platforms included commercial supercomputers, clusters of PC’s or workstations as well as custom-designed machines such as QCDOC and apeNEXT. The conclusion of this study was that custom- designed machines offer the best price-performance ratio and superior scalability [3].

6. The QCDOC supercomputer I have continued my collaboration with Columbia University, the RIKEN- BNL Research Center, IBM Research, and UKQCD on the construction of the massively parallel QCDOC computer for lattice QCD [4, 61. Large prototypes are already running physics code, and three machines of 10 TFlops (peak) each are currently being assembled at BNL.

Measurement time Detailed measurement as on the previous slide (vendor choice), presently, takes 6 hours per contact of the probe card, with a minimum of 12 contacts per sensor, giving (minimum) 72 working hours per sensor. - We are discussing ways to shorten this time.

Simple QA, presently, it takes 20 min per probe card contact, and so (minimum) 4 hours per sensor. For the QA measurement, we measure current and capacitance for every strip at one set voltage. This checks if each strip is alive or dead.

Complications in Extracting R as Luminosity Increases

e In Run 4, probability of BBCLLl trigger/crossing

e Roughly 1 percent of all triggers contained a second p p collision

e In Run 5, w 4 percent of all triggers may contain a second p p collision

0.02

At least two complications will result :

11) Min-bias trigger can only register 1 p p interaction/crossing

'2) With multiple p p interactions we are more likely to count events which shouldn't pass the +- we need to correct for possibility of multiple p p interactions/crossing

b l ' W h, vertex cut

+ If 1 event, RMS of xre,n = RMS of vertex width measured a t low luminosity + If n events, RMS of xre,on = RMS of vertex width measured a t low luminosity/& +

more likely to pass vertex cut

Complications in Extracting R as Luminosity Increases

How can we account for multiple p p interactions/crossing using the BBCLLl trigger rate?

0 Let p=average number of p p interactions/crossing passing vertex cut

a Let €=probability that one arm of BBC detects the collision

0 Let 6 = 1 - €=probability one arm misses the collision

Now extract the fraction of beam crossings yielding a min-bias trigger :

-P n 00

P(1+) = ce n; (1 - P ) ( 1 - S n > n=O
