Photon-neutrino interactions in magnetic fields

Abstract

The low-energy two neutrino-two photon interactions in the presence of homogeneous magnetic field are studied. The cross sections in external magnetic field are shown to be larger than in vacuum by factor $\sim (m_W/m_e{)}^4(B/B_c{)}^2$. The energy-loss rate due to the process $\gamma \gamma \to \nu \bar{\nu }$ in magnetic field is obtained.
