Description

We present results for the photon emission rate determined from the transverse channel vector correlator at fixed spatial momentum using two-flavor dynamical Wilson fermions at T ~ 250 MeV. We estimate the transverse channel spectral function using the continuum extrapolated correlator by applying various fit ansätze with a smooth matching to the NLO perturbative result. We confront our estimate based on this channel with the latest results of our collaboration based on the difference of the transverse and longitudinal channels.
