Photon-neutrino interactions in strong magnetic field

Abstract

The two-photon two-neutrino interaction induced by magnetic field is investigated. In particular the processes γ γ and γ γ are studied in the presence of strong magnetic field. An effective Lagrangian and partial amplitudes of the processes are presented. Neutrino emissivities due to the reactions γ γ and γ γ are calculated taking into account of the photon dispersion and large radiative corrections. A comparison of the results obtained with previous estimations and another inducing mechanisms of the processes under consideration is made.
