Probing the Dark Matter of the Three-loop Radiative Neutrino Mass Generation Model with the Cherenkov Telescope Array

Abstract We investigate the prospect of detecting Dark Matter (DM) candidate in three-loop radiative neutrino mass generation model extended with large electroweak multiplets Standard Model (SM) gauge group, at future imaging atmospheric Cherenkov telescope known as Telescope Array (CTA). find that addition such leads to a sizable Sommerfeld enhanced annihilation DM O (TeV) mass, into SM bosons which results continuum and line-like spectra very high energy (VHE) gamma-rays, therefore becomes observable for CTA. By considering VHE gamma-rays produced from Galactic center, we probe parameter space using sensitivity reach
