Shell-like structures in an expanding quark-antiquark plasma

Shell-like structures in an expanding quark-antiquark plasma.

The particle density distribution emerging from the solution of the Vlasov equation for relativistic, non-interacting particles with spherically symmetric initial conditions is shown to exhibit a shell-like structure for late fixed times in the center-of-mass (CM) frame of the system. A similar phenomenon was recently observed employing the test– particle method to solve the Vlasov equation for...

Chiral phase transition in an expanding quark-antiquark plasma.

We investigate the time evolution of a quark antiquark plasma by solving numerically the relativistic transport equations derived on the Hartree level from the Nambu-Jona-Lasinio model. We find that the phase transition in the expanding quark antiquark plasma is different as compared to that in a static plasma. The expansion competes with the transition and finally quark droplets will be formed...

Quark energy loss in an expanding quark-gluon plasma

We study the quark energy loss in an expanding quark-gluon plasma. The expanding plasma produced in high energy AA-collision is described by Bjorken’s model. The dependence of the energy loss on the infrared cutoff for the radiated gluons, on the quark mass, and on the initial conditions of QCD plasma is investigated. Study of the induced gluon radiation from a fast quark in a quark-gluon plasm...

Heavy quark in an expanding plasma in AdS/CFT

Using the Janik–Peschanski dual to a Bjorken flow, a Langevin equation is derived for a heavy quark in an expandingN = 4 supersymmetric Yang–Mills plasma. Such a plasma is characterized by a proper–time dependence of the temperature and corresponds to a system out of equilibrium. The analysis first focuses on a quark at rest in the plasma comoving frame. The case of a quark moving across a long...
