Two loop neutrino model and dark matter particles with global B−L symmetry

Baek, Seungwon; Okada, Hiroshi; Toma, Takashi

Abstract

We study a two loop induced seesaw model with global U(1)B−L symmetry, in which we consider two component dark matter particles. The dark matter properties are investigated together with some phenomenological constraints such as electroweak precision test, neutrino masses and mixing and lepton flavor violation. In particular, the mixing angle between the Standard Model like Higgs and an extra Higgs is extremely restricted by the direct detection experiment of dark matter. We also discuss the contribution of Goldstone boson to the effective number of neutrino species ΔNeff ≈ 0.39 which has been reported by several experiments.
