Abstract

We study the neutrino-photon processes such as γγ → νν + ̄, νγ, → νγ and νν + ̄ → γγ in a background magnetic field smaller than the critical magnetic field Bc = me2/e. Using Schwinger's formalism, we extract leading magnetic-field contributions to the above processes. Our result is valid throughout the kinematic regime where both neutrino and photon energies are significantly smaller than mW. We briefly discuss the astrophysical implications of our result.
