Περίληψη:
Within the context of the linear a-model, we investigate some
non-equilibrium phenomena that may occur during the two flavour QCD
chiral phase transition in heavy-ion collisions. We assume that the
chiral symmetry breaking is followed by a rapid quench and the system
falls out of thermal equilibrium. We study the mechanism for the
amplification of the pion field during the oscillations of the
sigma-field towards and around its new minimum. We show that the pion
spectrum can acquire a zone pattern with pronounced peaks at low
momenta, which corresponds to clustering behaviour in momentum space.
