Phys. Rev. D 56, 2548–2554 (1997)Thermal photon production rate from nonequilibrium quantum field theoryReceived 8 April 1997; published in the issue dated 1 September 1997 In the framework of closed time path thermal field theory we investigate the production rate of hard photons from a QCD plasma away from equilibrium. Dynamical screening provides a finite rate for chemically nonequilibrated distributions of quarks and gluons just as it does in the equilibrium situation. Pinch singularities are shown to be absent in the real photon rate even away from equilibrium. © 1997 The American Physical Society URL:
