摘要：

We construct a loop-induced seesaw model in a TeV scale theory with gauged U(1)(B-L) symmetry. Light neutrino masses are generated at two-loop level, and right-handed neutrinos also obtain their masses by a one-loop effect. Multicomponent dark matter (DM) particles are included in our model due to the remnant discrete symmetry after the B-L symmetry breaking and the Z(2) parity which is originally imposed to the model. We investigate the multicomponent DM properties in which we have two fermionic DM particles with different mass scales, O(10) GeV and O(100-1000) GeV. The former mass corresponds to the lightest right-handed neutrino mass induced by the loop effect, and the latter one to the Standard Model gauge singlet fermion. We show each of the DM annihilation processes and compare them to the observation of relic abundance, together with the constraints of lepton flavor violation and active neutrino masses. Moreover, we show that our model has some parameter region allowed by the direct detection result reported by XENON100, and it is possible to search the region by the future XENON experiment.
