Rate of photon production in the quark-gluon plasma from lattice QCD
Rate of photon production in the quark-gluon plasma from lattice QCD
We calculate the thermal rate of real-photon production in the quark-gluon plasma at a temperature of $T=254$ MeV using lattice QCD. The calculation is based on the difference between the spatially transverse and longitudinal parts of the polarization tensor, which has the advantage of falling off rapidly at large frequencies. …
