Abstract The structure of events in relativistic heavy ion collisions (RHIC), associated with chiral QCD phase transition, is investigated. In particular the density fluctuations of pions, emitted from the excited vacuum (at T ≈ T c ), are studied and classified in terms of intermittency patterns in rapidity space. For this purpose a Monte Carlo simulation of critical events in the central region is presented, on the basis of the O (4) theory of chiral phase transition. The universal character o...

The role of strange quark mass in chiral QCD phase transition is examined, in the environment of relativistic nuclear collisions. The term in the effective potential of the O(4) universality class satisfies the stability requirement for a tricritical behaviour and can be used in order to study critical fluctuations in either side of the tricritical point . Comparing the corresponding patterns of density fluctuations in rapidity, one may distinguish the effects due to first- or second-order phase...
