THE RADIATIVE DECAY OF A NEUTRINO WITH A MAGNETIC MOMENT IN A STRONG MAGNETIC FIELD WITH TAKING ACCOUNT OF THE POSITRONIUM INFLUENCE ON THE PHOTON DISPERSION

摘要

We study the process of the radiative decay of the neutrino with a magnetic moment in a strong magnetic field, with taking account of the influence of the positronium on the photon dispersion. The positronium contribution into the photon polarization operator leads to an essential modification of the photon dispersion law, and of the neutrino radiative decay amplitude. It has been shown that the probability of the neutrino radiative decay essentially increases under an influence of the positronium on the photon dispersion.
