  A new channel of direct photon production from a quark gluon plasma (QGP) is
explored. This process appears at Next-to-Leading-Order in the presence of a
charge asymmetry in the heated matter and may be effectively described as the
bremsstrahlung of a real photon from a thermal gluon. The photon production
from this new mechanism is calculated in the effective theory of QCD at high
temperature. The results show that the photon production rate may not as big as
the annihilation and Compton scattering at low baryon density, but could become
important in baryon-rich matter.
