Dileptons from the strongly interacting quark-gluon plasma (sQGP)
To address the dilepton production in a hot and dense medium – as created in heavy-ion collisions – we employ an up-to-date relativistic transport model, i.e. the Parton Hadron String Dynamics [1] (PHSD) that incorporates the explicit partonic phase in the early reaction region. The approach consistently describes the full evolution of a relativistic heavy-ion collision from the initial hard sc...
متن کاملHigh-energy dileptons from an anisotropic quark-gluon plasma
We calculate leading-order dilepton yields from a quark-gluon plasma which has a timedependent anisotropy in momentum space. Such anisotropies can arise during the earliest stages of quark-gluon plasma evolution due to the rapid longitudinal expansion of the created matter. A phenomenological model for the proper time dependence of the parton hard momentum scale, phard , and the plasma anisotro...
متن کاملDileptons from a Quark Gluon Plasma with Finite Baryon Density
We investigate the effects of a baryon-antibaryon asymmetry on the spectrum of dileptons radiating from a quark gluon plasma. We demonstrate the existence of a new set of processes in this regime. The dilepton production rate from the corresponding diagrams is shown to be as important as that obtained from the usual quark-antiquark annihilation. 25.70.Np, 12.38.Cy, 12.38.Mh Typeset using REVTEX 1
متن کاملRapidity distributions of dileptons from a hadronizing quark-gluon plasma.
It has been predicted that dilepton production may be used as a quark-gluon plasma probe. We calculate the rapidity distributions of thermal dileptons produced by an evolving quark-gluon plasma assuming a longitudinal scaling expansion with initial conditions locally determined from the hadronic rapidity density. These distributions are compared with Drell-Yan production and semileptonic charm ...
متن کاملSlavnov-taylor Identity for Nonequilibrium Quark-gluon Plasma
Within the closed-time-path formalism of nonequilibrium QCD, we derive a Slavnov-Taylor (ST) identity for the gluon polarization tensor. The ST identity takes the same form both in Coulomb and covariant gauges. Application to quasi-uniform quark-gluon plasma (QGP) near equilibrium or nonequilibrium quasistationary QGP is made.
