Spin light of neutrino in matter: a new type of electromagnetic radiation

Abstract

A short review of the properties of the spin light of neutrino ($SL\nu$) in matter, supplied with some historical notes on the discussed subject, is given. It is shown that consideration of the $SL\nu$ in matter in hep-ph/0605114 is based on erroneous calculations which ignore the fact that the energy-momentum conservation law can not be violated for this process. An attempt to rename the $SL\nu$ in matter, undertaken in hep-ph/0606262, is groundless.
