摘要：we expect chiral dynamics to play an important role. The model reproduces cpt prediction for the
spectrum of the Dirac operator and is consistent with the lattice data for pion and nucleon masses
in the range mp 300600 MeV.
Having checked that chiral dynamics is correctly encoded in the instanton model, we have
exploited our analytic handling on instanton-induced correlations to study the dynamical mechanisms
involved in the transition into the chiral regime, at a microscopic level. We have identified
a mass scale m? = 80 MeV above which we do not expect QCD correlators to be dominated by
chiral dynamics and above which quenched calculations should begin to approximate full QCD.
