X-ray line in Radiative Neutrino Model with Global U(1) Symmetry
Abstract
We study a three loop induced radiative neutrino model with global U(1) symmetry at TeV scale, in which we consider two component dark matter particles. We discuss the possibility to explain the X-ray line signal at about 3.55 keV recently reported by XMN-Newton X-ray observatory using data of various galaxy clusters and Andromeda galaxy. Subsequently, we also discuss to show that sizable muon anomalous magnetic moment, a discrepancy of the effective number of neutrino species N eff≈ 0.39, and scattering cross section detected by direct detection searches can be derived.
