Lepton flavor violation and scalar dark matter in a radiative model of neutrino masses

Understand

We consider a simple extension of the Standard Model that can account for the dark matter and explain the existence of neutrino masses.

• The model includes a vector-like doublet of SU(2), a singlet fermion, and two scalar singlets, all of them odd under a new Z$_2$ symmetry.
• Neutrino masses are generated radiatively by one-loop processes involving the new fields, while the dark matter candidate is the lightest neutral particle among them.
• We focus specifically on the case where the dark matter particle is one of the scalars and its relic density is determined by its Yukawa interactions.
