Transient photon production in a QGP
arXiv:hep-ph/0408094 · doi:10.1063/1.1843615
Abstract
We discuss the shortcomings of a formula that has been used in the literature to compute the number of photons emitted by a hot or dense system during a finite time, and show that the transient effects it predicts for the photon rate are unphysical.
