High energy neutrino absorption by W production in a strong magnetic field
arXiv:1002.3804 · doi:10.1016/j.physletb.2010.05.059
Abstract
An influence of a strong external magnetic field on the neutrino self-energy operator is investigated. The width of the neutrino decay into the electron and W boson, and the mean free path of an ultra-high energy neutrino in a strong magnetic field are calculated. A kind of energy cutoff for neutrinos propagating in a strong field is defined.
