Description

I will discuss recent progress in constraining the thermal photon emission rate of the quark-gluon plasma from lattice QCD simulations at temperatures of around 250 MeV relevant for heavy-ion collision phenomenology.
Our recent analysis of the tranverse vector current correlator complements our earlier first computation of the continuum current correlators with Nf=2 dynamical Wilson fermions in a different channel.
In the second part of the talk, the connection between the production of virtual photons (dileptons) and the process of a light lepton scattering on the plasma will be outlined.
Knowledge of the structure functions which parameterize this process might help to constrain dilepton rates as well as to help elucidate the fundamental structure of the quark-gluon plasma.
