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 \lessim T from a quark-gluon plasma. In particular the cancellation of the infrared singularity by medium effects is discussed in detail.

Note:
