dc.description.abstract	We show the mathematical formulation of the process of pair production in electromagnetic fields forspinless particles. We compute the probability that ? pairs are created in the semiclassical approximation,and we prove that, in this approach, the pair creation phenomenon is a stochastic Poisson process. Finally,we give a rigorous demonstration and a suitable interpretation of the Schwinger formula.
