Abstract
Using an impact parameter formulation, differential probability distributions and cross sections for the production of lepton pairs via the photon-photon mechanism are calculated for relativistic heavy-ion collisions. The characteristic features of lepton pair production in disruptive as well as in non-disruptive A-A collisions are studied. Cross sections can be large, the very low k ⊥-values of the pairs will help to distinguish these pairs from the ones originating from other sources like Drell-Yan or thermal production.
