Hard photon production rate of a quark-gluon plasma at finite quark chemical potential

Abstract

We compute the photon production rate of a quark-gluon plasma (QGP) at finite quark chemical potential $\mu$ using the Braaten-Pisarski method, thus continuing the work of Kapusta, Lichard, and Seibert who did the calculation for $\mu =0$.
