摘要We investigate hard photon production in a chemically equilibrating quark-gluons plasma with finite baryon density at one-loop and two-loop based on Juttner distribution of partons of the system. We find that the photon yield increases obviously with increasing the initial quark chemical potential, and the photon production is dominated by early times. In addition, obvious difference between the calculated production and the one in the thermodynamic equilibrium system shows that the study of photon production in the chemically equilibrating system is very significant.
