Perturbative and Nonperturbative Em Lepton Pair Production in Relativistic Heavy-Ion Collisions
In this talk, I will focus on electromagnetic dilepton production from the QED-vacuum in relativistic heavy-ion collisions. Heavy ions in relativistic motion generate strong time-dependent EM fields with large Fourier components which give rise to sizable pair production. There are several motivations for our studies: Lepton pair production by hadronic (Drell-Yan) processes has been widely discussed as a possible signature of the quark-gluon plasma formation1. The dominant background will come from electromagnetic sources and could even mask the signals from the plasma phase2.
