  A new channel of direct photon production from a quark gluon plasma (QGP) is
explored in the framework of high-temperature QCD. This process appears at
next-to-leading order, in the presence of a charge asymmetry in the excited
matter. The photon production rate from this new mechanism is suppressed
compared to the QCD annihilation and Compton scattering at low baryon density
but assumes importance in baryon-rich matter.
