The Mechanism Of Neutrino Mass Circle Generation

Current experiments show that neutrino masses are much smaller than the other fermion-s. In theory, the tiny masses are naturally produced through seesaw mechanism or loop ra-diative corrections. In this paper we supplement the SM field with a scalar triplet, a charged scalar singlet and two Majorana fermions. Due to the extra Z2symmetry, neutrino masses can only arise from the three-loop diagrams, and along with other suppressive factors we can make their masses below0,1eV. Moreover, the lightest Majorana particle can be a candidate for dark matter, and some new particle masses in the model are hundreds of GeV, which is the reach of recent experiments. Further, we also discuss the neutrino physics, lepton flavor violation, muon anomalous magnetic moment and dark matter data impose restrictions on model parameters.
