Survival Probabilities of Disoriented Chiral Domains in Relativistic Heavy Ion Collisions

Abstract

By using a dynamical transport code we show that chirally disoriented domains might survive the hadronization phase in a central relativistic heavy ion collision. A successful measurement of such domains after freeze-out will depend on the domain size and the manifestation of the disorientation in the low part of the charged pion momentum spectrum. We investigated the measurement of the transverse momentum and the pseudo-rapidity spectrum of pions below 200 MeV/c. In all cases the successful determination of a realistic domain requires first and second moment analyses of the phase space.
