Stochastic Disoriented Chiral Condensates
Abstract
Applying a Langevin description of the linear sigma model we investigate four different scenarios for the evolution of a disoriented chiral condensate: annealing or quench with initial conditions governed by effective `light' or physical mass pions. We present pion number distributions estimated from the zero mode (i.e. k=0-field) component. The best DCC signal is expected for the quench scenario with initial conditions centered around zero as would be the case of effective light `pions' close to the phase transition. Our investigations support the idea of looking for DCC formation in individual events.
