Title: Strong evidence for spontaneous chiral symmetry breaking in (quenched) QCD
Abstract: We calculate the chiral condensate 〈ψψ〉 for all quark masses using Kogut-Susskind fermions in lattice-regularized quenched QCD. The large volume behaviour of 〈ψψ〉 at small quark masses demonstrates that the explicit U(1) chiral symmetry is spontaneously broken. We perform the calculation for β = 5.1 to59 and find very good continuum renormalization group behaviour. We infer that the spontaneous breaking we observe belongs to continuum QCD. This constitutes the first unambiguous demonstration of spontaneous chiral symmetry breaking in continuum quenched QCD.
