Neutrino masses in the minimal gauged supersymmetry
arXiv:1803.04599 · doi:10.1103/PhysRevD.97.055036
Abstract
We present the radiative corrections to neutrino masses in a minimal supersymmetric extension of the standard model with local symmetry. At tree level, three tiny active neutrinos and two nearly massless sterile neutrinos can be obtained through the seesaw mechanism. Considering the one-loop corrections to the neutrino masses, the numerical results indicate that two sterile neutrinos obtain masses and the small active-sterile neutrino mixing angles. The lighter sterile neutrino is a very interesting dark matter candidate in cosmology. Meanwhile the active neutrinos mixing angles and mass squared differences agree with present experimental data.
