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…

It is shown that, in a broad class of models, where the sterile neutrino dark matter relic density is generated by a light neutrinophilic mediator, there must be a lower bound on the amount of extra radiation in early Universe, in particular, ΔN_{eff}>0.12 at the cosmic microwave background (CMB) epoch.

This model is reexamine and it is found that hot, warm, and cold dark matter are all possibilities and the number density of sterile neutrinos is proportional to [mu][sup 2]/M so that the energy density today is independent of M, which is crucial in determining the large scale structure of the Universe.

Production and evolution of perturbations of sterile neutrino dark matter
Sterile neutrinos, fermions with no standard model couplings [SU(2) singlets], are predicted by most extensions of the standard model, and may be the dark matter. I describe the nonthermal production
