摘要:
We perform a systematic study of the Dirac neutrino masses which arise from dimension five and dimension six effective operators. We identify all possible realizations of these operators at tree level and one-loop level. The corresponding predictions for the particle content and neutrino mass matrix are presented. The electrically neutral particle mediating the loop diagram could be dark matter candidate. We give the possible dark matter particles and the restrictions on the parameter α for each model. We also studied the flavor mixing of leptons, including the generalized CP symmetry, we have performed a comprehensive scan of leptonic mixing patterns which can be obtained from finite discrete groups with order less than 2000. The resulting lepton mixing matrices admit a good agreement with experimental data.
