Abstract

We consider the thermal emission rate of dileptons from a QCD plasma in the small invariant mass (Q² ∼ \gs² T²) but large energy (q⁰ \gsim T) range. We derive an integral equation which resums multiple scatterings to include the LPM effect; it is valid at leading order in the coupling. Then we recast it as a differential equation and show a simple algorithm for its solution. We present results for dilepton rates at phenomenologically interesting energies and invariant masses.
