Dilepton emission from an equlibrating non-abelian plasma

Abstract

We study dilepton production from a thermally equilibrating quark-gluon plasma expected to be formed in ultra relativistic heavy-ion collisions. The pre-equilibrium dynamics of quark-gluon plasma is studied within the color flux-tube model by solving non-abelian relativistic transport equations. This dilepton rate crucially depends on the collision time of the plasma. The results are compared with the Drell-Yan productions. We suggest that a measurement of this rate at RHIC and LHC will determine the initial field energy density.
