4 Nov 2002 | Journal: | JHEP 0212 (2002) 006 | Subject: | hep-ph | Affiliation: | LAPTH, Annecy), F. Gelis (SPhT, Saclay), G.D. Moore (McGill University), H. Zaraket (Winnipeg University | Abstract: | We consider the thermal emission rate of dileptons from a QCD plasma in the small invariant mass ($Q^2 sim gs^2 T^2$) but large energy ($q^0 gsim T$) 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. | Source: | arXiv, hep-ph/0211036 | Services: | Forum | Review | PDF | Favorites |
