Generation of a radiative neutrino mass in the linear seesaw framework, charged lepton flavor violation, and dark matter

摘要

We investigate a model with local U(1)_(B-L) and discrete Z2 symmetries where two types of weak isospin singlet neutrinos, vectorlike charged leptons, and exotic scalar fields are introduced. The linear seesaw mechanism is induced at the one-loop level through Yukawa interactions associated with the standard model leptons and exotic fields. We also discuss lepton flavor violation and a muon anomalous dipole magnetic moment induced by the new Yukawa interaction. In addition, our model has dark matter candidate which is the lightest Z_2 odd neutral particle. We calculate the relic density and constraints from direct detection.
