The amplitude of lepton-pair production in relativistic ion collisions beyond the perturbative theory

arXiv:hep-ph/0504249

Abstract

We investigate the structure of some first terms of Watson series representing the amplitude of lepton-pair production in the ion collisions. It is shown that infrared instabilities of individual terms trend to cancel each other providing the infrared stability of whole amplitude.
