Abstract: We use the real-time Keldysh formalism to investigate finite lifetime effectson the photon emission from a quark-gluon plasma QGP. We provide an ansatzwhich eliminates the divergent contribution from the vacuum polarization andrenders the photon spectrum UV-finite if the time evolution of the QGP isdescribed in a suitable manner.
