Abstract
We study neutrinos and dark matter based on a gauged U(1)R symmetry in the framework of a radiative seesaw scenario.We identify the dark matter as a bosonic particle that interacts with the quark and the lepton sectors through vector-like heavier quarks and leptons.The dark matter also plays a role in generating the neutrino mass matrix with the neutral heavier fermions.We explore several constraints for the masses and the couplings related to the dark matter by computing the relic density and the scattering cross sections for direct detection methods, taking into consideration neutrino oscillations, lepton flavor violations, and the muon anomalous magnetic moment.Finally, we mention the semileptonic decays and the neutral meson mixings that occur through the dark matter by one-loop box diagrams.
