Heavy dileptons from nonequilibrium QGP

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

The rate of emission of heavy dileptons from QGP is found without an assumption of its complete thermal equilibrium. We base on the real-time quantum field kinetic approach [1] and use the expansion up to the second order with respect to strong coupling constant gg. The final answer is not free from the collinear singularities and we show that this is the actual issue. As a result the main contribution to the rate of the heavy dileptons production at M/T10M/T \sim 10 comes from the process qqˉgγq\bar{q}g\rightarrow \gamma^{*}.
