Description
We analyze the production rates of photons and dileptons from the deconfined medium using a quark propagator obtained from a first principle lattice QCD numerical simulation. We calculate the production rates non-perturbatively at two temperatures above $T_{\rm c}$. The photon-quark vertex is determined gauge-invariantly, so as to satisfy the Ward-Takahashi identity. The photon production rate shows an enhancement and a peculiar structure reflecting kinematics of quasi-particles. We discuss the origin of the structure.
