Content
In the context of relativistic heavy-ion collisions, an excess has been detected in the yield of photons and in the strength of the elliptic flow, sometimes referred to as the photon puzzle. It has been argued that, due to the presence of strong magnetic fields in these systems, new channels of photon production can be present and contribute to this excess. To this aim, we study the gluon fusion into one photon, described by the two-gluon one-photon vertex and give its general structure. We also obtain an explicit expression at a one-loop order in the intermediate field regime.
