Impact-parameter dependence of the electromagnetic particle production in ultrarelativistic heavy-ion collisions

Abstract
The cross section for the electromagnetic production of different particles in heavy-ion collision is derived within the external field approach. Introducing polarized photon-fusion cross sections, it is possible to generalize the equivalent photon method to describe the impact-parameter dependence of the particle production. The impact-parameter dependent production of scalar and pseudoscalar (spin 0) bosons, charged (spin 0) boson pairs, and fermion pairs is discussed.
