Abstract
Next-to-leading order analyses of the dilepton production rate from a hot QCD plasma are reviewed. In general, the photon invariant mass is taken to be in the range K2∼(πT)2, permitting thereby for an interpolation between an OPE computation in a hard regime K2≫(πT)2 and an LPM resummed computation in a soft regime 0<K2≪(πT)2. If the computations are extended into the spacelike domain K2<0 in the future, they can also be systematically compared with lattice results at non-zero momentum.
