In this paper, we extend the study of bremsstrahlung photon production in a quark-gluon plasma to the cases of soft static photons and hard real photons. The general framework of this study is the effective perturbative expansion based on the resummation of hard thermal loops. Despite the fact that bremsstrahlung only comes at two loops, we find that in both cases it generates contributions of the same order of magnitude as those already calculated by several other groups at one loop. Furthermore, a new process contained in the two-loop diagrams dominate the emission of a very hard real photon. In all cases, the rate of real or virtual photon production in the plasma is appreciably increased compared to the one-loop predictions.

Thermal dilepton production within conformal viscous Gubser flow
Thermal dilepton yields and effective temperatures are computed for conformal viscous Gubser flow, showing larger yields for lower q (larger systems) and higher effective temperatures for smaller systems.

Beyond leading-logarithm photon production from two-loop diagrams in a hot QCD medium
Two-loop imaginary-time QCD self-energies yield the same hard-photon LL and BLL rates as kinetic theory for Compton and qq̄ annihilation, with topology II vanishing on-shell but restoring the Ward identity.
