Photon-Neutrino Interactions in Magnetic Field through Neutrino Magnetic Moment
Ashok Goyal
Abstract
We study the neutrino-photon processes like γγνν in the presence of uniform external magnetic field for the case when neutrinos can couple to the electromagnetic field directly through their dipole magnetic moment and obtain the stellar energy loss. The process would be of special relevance in astrophysical situations where standard left-handed neutrinos are trapped and the right handed neutrinos produced through the spin flip interaction induced by neutrino magnetic moment alone can freely stream out.
