抄録

We demonstrate that the chiral phase transition is automatically incorporated in the numerical simulations of the classical equations of motion in the linear a-model. We find that domains of disoriented chiral condensate (DCC) 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 in ultrarelativistic heavy ion collisions. At the end, we discuss the possibility to create DCC in laboratories.
