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 would not only explain the observed neutrino oscillations, but could also be responsible for several phenomena in cosmology, including the baryon asymmetry of the universe, dark matter and dark radiation. A crucial parameter in this context is their mass, which in principle could lie anywhere between the eV scale and GUT scale. The implications for experiments and cosmology strongly depend on the choice of the mass scale. I review recent progress in the phenomenology of right handedneutrinos with different masses, focussing on scenarios where they lie at or below the TeV scale. I put special emphasis on the possibility to discover the heavy neutrinos that are responsible for leptogenesis in near future experiments, such as LHC, BELLE II and SHiP.
