The Phenomenology of Right Handed Neutrinos
Abstract
Neutrinos are the only particles in the Standard Model of particle physics that have only been observed with left handed chirality to date. If right handed neutrinos exist, they could be responsible for several phenomena that have no explanation within the Standard Model, including neutrino oscillations, the baryon asymmetry of the universe, dark matter and dark radiation. After a pedagogical introduction, we review recent progress in the phenomenology of right handed neutrinos. We in particular discuss the mass ranges suggested by hints for neutrino oscillation anomalies and dark radiation (eV), sterile neutrino dark matter scenarios (keV) and experimentally testable theories of baryogenesis (GeV to TeV). We summarize constraints from theoretical considerations, laboratory experiments, astrophysics and cosmology for each of these.
Sterile neutrinos could also be a lot heavier than regular neutrinos, those kind of sterile neutrinos are ideal candidates for explaining dark matter and the matter-antimatter asymmetry https://arxiv.org/abs/1303.6912 Just as I am disappointed that "global warming" changed into…

The known (non-sterile) neutrinos are very light, but there's no particular reason a hypothetical sterile neutrino would be.You can cook up sterile neutrinos with very large masses if you want to https://arxiv.org/abs/1303.6912
