Photon-neutrino interactions in a magnetic field through the neutrino magnetic moment - art. no. 013005

We study neutrino-photon processes such as gamma gamma-->nu<(<nu>)over bar> in the presence of a uniform external magnetic field for the case when neu trinos can couple to the electromagnetic field directly through their dipol e 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 Aip interaction induced by the neutrino magnetic moment alone can free ly stream out.
