Dynamical formation of domains in net-baryon density at the QCD phase
transition    [PDF]

Christoph Herold, Marlene Nahrgang, Igor Mishustin, Marcus Bleicher

We consider the (3+1) dimensional expansion and cooling of the chirally-restored and deconfined matter at finite net-baryon densities as created in heavy-ion collisions. In our approach, chiral fields and the Polyakov loop propagate explicitly within a medium represented by a quark-antiquark fluid. The interaction between the fields and the fluid leads to dissipation and noise, which in turn affect the field fluctuations. For the first time in a realistic dynamical study, we demonstrate the possibility of domain formation in a first-order phase transition of QCD matter.
