Production of energetic dileptons with small invariant masses from the quark-gluon plasma

Abstract

The resummation technique of Braaten and Pisarski is used for a complete calculation of the ${\alpha }^2{\alpha }_s$-contribution to the production rate of dileptons with energy E >> T and invariant mass M <~ T from a quark-gluon plasma. In particular the cancellation of the infrared singularity by medium effects is discussed in detail.
