Abstract

Sterile right-handed neutrinos can be naturally embedded in a low scale gauged U(1){sub B-L} extension of the standard model. We show that, within a low reheating scenario, such a neutrino can be produced via a novel manner, namely scattering through Z' gauge boson, and becomes an interesting dark matter candidate. In addition, we show that if the neutrino mass is of the order of MeV, then it accounts for the measured dark matter relic density and also accommodates the observed flux of 511 keV photons from the galactic bulge.

Sterile neutrino dark matter in B-L extension of the standard model and galactic 511 keV line

Journal Article Khalil, Shaaban; Seto, Osamu - Journal of Cosmology and Astroparticle Physics

Sterile right-handed neutrinos can be naturally embedded in a low scale gauged U(1){sub B-L} extension of the standard model. We show that, within a low reheating scenario, such a neutrino is an interesting dark matter candidate. We emphasize that if the neutrino mass is of the order of MeV, then it accounts for the measured dark matter relic density and also accommodates the observed flux of 511 keV photons from the galactic bulge.

Freeze-in production of sterile neutrino dark matter in U(1){sub B−L} model

Journal Article Biswas, Anirban; Gupta, Aritra - Journal of Cosmology and Astroparticle Physics

With the advent of new and more sensitive direct detection experiments, scope for a thermal WIMP explanation of dark matter (DM) has become extremely constricted. The non-observation of thermal WIMP in these experiments has put a strong upper bound on WIMP-nucleon scattering cross section and within a few years it is likely to overlap with the coherent neutrino-nucleon cross section. Hence in all probability, DM may have some non-thermal origin. In this work we explore in detail this possibility of a non-thermal sterile neutrino DM within the framework of U(1){sub B−L} model.

Higgs portal dark matter in the minimal gauged U(1){sub B-L} model

Journal Article Okada, Nobuchika; Seto, Osamu - Physical Review. D, Particles Fields

We propose a scenario of the right-handed neutrino dark matter in the context of the minimal gauged U(1){sub B-L} model by introducing an additional parity which ensures the stability of dark matter particle. The annihilation of this right-handed neutrino takes place dominantly through the s-channel Higgs boson exchange, so that this model can be called the Higgs portal dark matter model. We show that the thermal relic abundance of the right-handed neutrino dark matter with the help of Higgs resonance can match the observed dark matter abundance. In addition, we estimate the cross section with nucleon and show that themore »« less

Dark-matter sterile neutrinos in models with a gauge singlet in the Higgs sector

Journal Article Petraki, Kalliopi; Kusenko, Alexander - Physical Review. D, Particles Fields

Sterile neutrino with mass of several keV can be the cosmological dark matter, can explain the observed velocities of pulsars, and can play an important role in the formation of the first stars. We describe the production of sterile neutrinos in a model with an extended Higgs sector, in which the Majorana mass term is generated by the vacuum expectation value of a gauge-singlet Higgs boson. In this model the relic abundance of sterile neutrinos does not necessarily depend on their mixing angles, the free-streaming length can be much smaller than in the case of warm dark matter produced bymore »« less

Origin of sterile neutrino dark matter via secret neutrino interactions with vector bosons

Journal Article Kelly, Kevin; Sen, Manibrata; Tangarife, Walter; ... - Physical Review D

Secret neutrino interactions can play an essential role in the origin of dark matter. We present an anatomy of production mechanisms for sterile neutrino dark matter, a keV-scale gauge-singlet fermion that mixes with active neutrinos, in the presence of a new vector boson mediating secret interactions among active neutrinos. We identify three regimes of the vector boson’s mass and coupling where it makes a distinct impact on dark matter production through the dispersion relations and/or scattering rates. We also analyze models with gauged Lμ-Lτ and B-L numbers which have a similar dark matter cosmology but different vector boson phenomenology. Wemore »« less
