Conference paper


The quantum theory of the spin light of neutrino (SLν) exactly accounting for the effect of the background matter is developed. Contrary to the already performed studies of the SLν, in this paper we derive expressions for the SLν rate and power and also for the emitted photon’s energy that are valid for an arbitrary value of the matter density including the case of a very dense matter. The spatial distribution of the radiation power and the dependence of the emitted photon’s energy on the direction of radiation are also studied in detail for the first time. We analyze the SLν polarization properties and show that in a wide range of the neutrino momentum and density of matter the SLν radiation is nearly totally circular polarized. Conditions for the effective SLν photon propagation in the electron plasma are discussed.
