Neutrino Radiative Decay in an External Electromagnetic Field via Vector Leptoquark

N. V. Mikheev, L. A. Vassilevskaya, M. L. Zilberman

The massive neutrino radiative decay ${\nu }_i\to {\nu }_j\gamma$ ($i\ne j$) is investigated within the Minimal Quark-Lepton Symmetry of the Pati-Salam type based on the $SU(4)_V \time…
