HARO, J.. The semiclassical theory of quantized fields in classical electromagnetic backgrounds. Rev. mex. fis. [online]. 2004, vol.50, n.6, pp.553-561. ISSN 0035-001X.

We formulate mathematically the process of pair production in electromagnetic fields for spinless particles. We compute the probability that n pairs are created in the semiclassical approximation, and herein we prove that the pair creation phenomenon is a stochastic Poisson process. Finally, we prove rigorously and interpret suitably the Schwinger formula.

Palabras llave : Pair production; Schwinger's formula; semiclassical approach.
