Chiral symmetry breaking and cooling in lattice QCD

R. M. Woloshyn

Frank Lee

Abstract: Chiral symmetry breaking is calculated as a function of cooling in quenched lattice QCD. A non-zero signal is found for the chiral condensate beyond one hundred cooling steps, suggesting that there is chiral symmetry breaking associated with instantons. Quantitatively, the chiral condensate in cooled gauge field configurations is small compared to the value without cooling.

Correlation between confinement and chiral-symmetry breaking in the dual Higgs theory

We study the correlation between confinement and dynamical chiral-symmetry breaking (DχSB) in the dual Ginzburg-Landau (DGL) theory using the effective potential formalism. The DGL theory is an infrared effective theory based on the dual Higgs mechanism, and provides the nonperturbative gluon propagator, which leads to the linear quark potential. The screening effect for the confining potential can be obtained by introducing the infrared cutoff corresponding to the hadron size. We formulate the effective potential for DχSB in the DGL theory, and find the vacuum instability against quark condensation. To extract confinement effect, we separate the effective potential into the confinement part and others by dividing the confinement term from other terms in the gluon propagator in the DGL theory. The confinement part provides the dominant contribution to DχSB, which is regarded as monopole dominance for DχSB. The relevant energy for DχSB is found to be the infrared region below 1GeV. Monopole dominance for the DGL propagator is also found in the intermediate region, 0.2fm

Recombination of dyons into calorons inSU(2)lattice fields at low temperatures

et al. 2004

By cooling of equilibrium lattice fields at finite temperature in SU (2) gauge theory it has been shown that topological objects (calorons) observed on the lattice in the confined phase possess a dyonic substructure which becomes visible under certain circumstances. Here we show that with the increasing temporal lattice extent the distribution in the caloron parameter space is modified such that the calorons appear non-dissociated into constituent dyons. Still the calorons have nontrivial holonomy which is demonstrated by the Polyakov line behaviour for these configurations. At vanishing temperature (on a symmetric lattice) topological lumps obtained by cooling show rotational symmetry in 4D for the action density, but a characteristic internal double peak structure of Polyakov lines with respect to all (temporal and spatial) directions.
