Contribution of Higgs bosons to the elastic scattering amplitude of a lepton in a flat wave field

The contribution of pseudoscalar particles (⁰-mesons and Higgs bosons) to the elastic scattering amplitude of a lepton in the field of a flat elliptically polarized electromagnetic wave is computed by using dispersion relations. The polarization effects are considered. By a limit transition, the contribution of pseudoscalar particles to the amplitude is found in a constant crossed field.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 1, pp. 85–90, January, 1991.
