ANOMALOUS TRANSVERSE-DISTRIBUTION OF PIONS AS A SIGNAL FOR THE PRODUCTION OF DISORIENTED CHIRAL CONDENSATES

We give evidence that the production of disoriented chiral condensates during a nonequilibrium phase transition can lead to an anomalous tra nsverse distribution of secondary pions when compared to a more conven tional boost invariant hydrodynamic flow in local thermal equilibrium. Our results pertain to the linear sigma model, treated in leading ord er in large N, in a boost invariant approximation. We also show that t he interpolating number density of the field theory calculation plays the role of a classical relativistic phase space number distribution i n determining the momentum distribution of pions in the center of mass frame.
