Resonance neutrino bremsstrahlung $\nu \to \nu \gamma$ in a strong magnetic field

Abstract

High energy neutrino bremsstrahlung $\nu \to \nu + \gamma$ in a strong magnetic field ($B \gg B_s$) is studied in the framework of the Standard Model (SM). A resonance probability and a four-vector of the neutrino energy and momentum loss are presented. A manifestation of the neutrino bremsstrahlung in astrophysical cataclysm of type of a supernova explosion or a merger of neutron stars, such as an possible origin of cosmological $\gamma$-burst is discussed.
