Chiral symmetry breaking in the action formulation of lattice gauge theory

Abstract

We show, in the euclidean path-integral formulation of strong-coupling lattice gauge theory, that continuous chiral symmetry is dynamically broken, and obtain the standard current algebra result that m pseudo-Goldstone 2 ∼ m quark 〈 ψψ〉 . We also remark that the center of the gauge group does not seem very relevant for this result; chiral symmetry breaking is a property of strong-coupling lattice theories both in the case where quark color is confined, and also in the case where it is screened by gauge field fluctuations.
