Transition radiation in QCD matter

Transition Radiation in QCD matter

In ultrarelativistic heavy ion collisions a finite size QCD medium is created. In this paper we compute radiative energy loss to zeroth order in opacity by taking into account finite size effects. Transition radiation occurs on the boundary between the finite size medium and the vacuum, and we show that it lowers the difference between medium and vacuum zeroth order radiative energy loss relati...

Transition radiation by matter-wave solitons in optical lattices.

We demonstrate that matter-wave solitary pulses formed from Bose condensed atoms moving inside optical lattices continuously radiate dispersive matter waves with prescribed momentum. Our analytical results for the radiation parameters and the soliton decay rate are found to be in excellent agreement with numerical modeling performed for experimentally relevant parameters.

Chiral Phase Transition in QCD

We employ non–perturbative flow equations to compute the equation of state for two flavor QCD within an effective quark meson model. This yields the temperature and quark mass dependence of quantities like the chiral condensate or the pion mass. Our treatment covers both the chiral perturbation theory domain of validity and the domain of validity of universality associated with critical phenome...

Deconfining transition in Full QCD

All of them have a maximum at the same value of T , for a given mq, which defines the line in Fig. 1. For mq > 3 GeV, the maxima of χL diverge proportionally to the volume V , indicating a first order transition. At mq = 0 there are theoretical reasons and numerical indications that the transition is second order [3,1,2]. At intermediate values of mq (tiny part of the line in Fig. 1) the suscep...
