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 $\mu =0$.Comment: 9 pages, revtex, no figures, error in soft part corrected, figures available at ftp://theorie.physik.uni-giessen.de/usr/users/ftp/photon
