Satisfies lepton flavor violation and dark matter relic density constraints.

Provides potential explanations for muon anomalous magnetic moment.

Abstract

We propose a two-loop induced neutrino mass model, in which we show some bench mark points to satisfy the observed neutrino oscillation, the constraints of lepton flavor violations, and the relic density in the co-annihilation system satisfying the current upper bound on the spin independent scattering cross section with nuclei. We also discuss new sources of muon anomalous magnetic moment.
