Sterile neutrino dark matter in the super-weak model

High Energy Physics - Phenomenology 2022-10-31 v1

Abstract

The super-weak model is a U(1) extension of the Standard Model. In addition to a mediator ZZ', a singlet scalar field χ\chi is added to deal with the meta-stability of the SM vacuum, and right-handed neutrinos are introduced to account for the non-vanishing neutrino masses. We demonstrate that the lightest right-handed neutrino is a possible dark matter candidate with masses of O(10) MeV\mathcal{O}(10)~\mathrm{MeV} via the resonant freeze-out scenario. The dark matter production is explored and the available parameter space is discussed from the point of view of various experiments and beyond SM aspects.
