Two loop Induced Dirac Neutrino Model and Dark Matters with Global $U(1{)}^{\prime }$ Symmetry

Abstract

We propose a two loop induced Dirac type neutrino model at TeV scale. Subsequently, three types of dark matter particles; fermion and two bosons, are naturally introduced. Here we discuss to analyze two possibilities; two component dark matter scenario (Dirac fermion and complex boson) and single dark matter one (another real boson), comparing to current experimental data such as Planck/WMAP and LUX. We briefly mention the possibility to explain the discrepancy of the effective number of neutrino species reported by several experiments.
