PION-PRODUCTION FROM BAKED-ALASKA DISORIENTED CHIRAL CONDENSATE

We study the various stages of the evolution of chiral condensates dis oriented via the ''baked-Alaska'' mechanism, in which the condensates are described as the products of external sources localized on the lig ht cone. Our analysis is based on the classical equations of motion of either the linear or the nonlinear sigma model. We use the associated framework of coherent states and, especially, their source functions to make the connection to the distribution functions for the produced particles. We also compare our classical approach with a mean-field ca lculation which includes a certain class of quantum corrections. [S055 6-2821(97)07123-3].
