Radiative Transition of Massless Neutrino in Strong Magnetic Field

Radiative transition of massless neutrino ${\nu }_l\to {\nu }_l+\gamma$ ($l = e, \mu, \tau$) in a strong magnetic field is investigated in the framework of the Standard Model. The process probability and the mean values of the neutrino energy and momentum loss are presented. Possible astrophysical manifestation of the process considered is analysed.
