Two Loop Radiative Seesaw and X-ray line Dark Matter with Global U(1) Symmetry

Abstract

We study a two loop induced radiative neutrino model with global $U(1)$ symmetry at 1 GeV scale, in which we explain the X-ray line at 7.1 keV of dark matter candidate reported by XMN-Newton X-ray observatory using data of various galaxy clusters and Andromeda galaxy. We also discuss Higgs sector, lepton flavor violation processes, and a physical Goldstone boson.
