چکیده
We calculate the large-volume and small-mass dependences of the quark condensate in quenched QCD using Neuberger's operator. We find good agreement with the predictions of quenched chiral perturbation theory, enabling a determination of the chiral lagrangian parameter Σ, up to a multiplicative renormalization.

A single species of staggered fermion represents four degenerate quarks in the continuum limit, but at finite lattice spacing the SU(4) flavor symmetry is broken down to a discrete subgroup[1]. We have found, however, that there is a substantial restoration of the flavor symmetry in the chiral limit, at least in the pion sector [2]. We give here a description of our conclusions and an outline o...

We study the quenched lattice QCD using domain-wall fermions at β = 6.0. Behaviors of both pion mass and the explicit breaking term in the axial Ward-Takahashi identity support the existence of the chiral zero modes. We observe a good agreement between the pion decay constants fπ from both the conserved axial current and the local current perturbatively renormalized at 1-loop. Finally the possi...

This report is based on the work done together with J.B. Kogut and C.G. Strouthos. We study a Yukawa theory with spontaneous chiral symmetry breaking and with a large number N of fermions near the finite temperature phase transition. Critical properties in such a system can be described by the mean field theory very close to the transition point. We show that the width of the window of non-triv...

The static potential in the 3d SU(2) Higgs model is computed by a variational calculation employing Wilson loops and two-meson operators. String breaking is demonstrated numerically, the breaking scale is determined and the results are compared with a quenched calculation.
