Electromagnetic catalysis of the radiative transitions of ${\nu }_i\to {\nu }_j\gamma$ type in the field of an intense monochromatic wave

Abstract

The radiative decay of the massive neutrino ${\nu }_i\to {\nu }_j\gamma$ in a circularly polarized electromagnetic wave is investigated within the Standard theory with lepton mixing. The decay probability in the wave field does not contain a threshold factor $\sim (1-m_i/m_j)$ as opposed to the decay probability in a vacuum or in a constant uniform external field. The phenomenon of the gigantic enhancement ( $\sim 10^{33}$ ) of the neutrino decay probability in external wave field is discovered. The probability of the photon splitting into the neutrino pair is obtained. (Published in Phys.Lett.B 321 (1994) 108).
