Abstract:
We demonstrate that semiclassical fluctuations, their relaxation, and the chiral phase transition are automatically incorporated in the numerical simulations of the classical equations of motion in the linear -model when longitudinal and transverse expansions are included. We find that domains of disoriented chiral condensate with 4--5 fm in size can form through a quench while an annealing leads to domains of smaller sizes. We also demonstrate that quenching cannot be achieved by relaxing a chirally symmetric system through expansion.- sigma model: nonlinear
