Lepton Number Violating

We consider all possible scalar bilinears, which couple to two fermions of the standard model. The various baryon and lepton number violating couplings allowed by these exotic scalars are studied. We then discuss which are constrained by limits on proton decay (to a lepton and a meson as well as to three leptons), neutron–antineutron oscillations, and neutrinoless double beta decay.

The Universe

The abundances of baryons and leptons are not only closely related to each other and to the generation of neutrino masses but may also be linked to the dark matter in the Universe. In this paper we review how a consistent physics beyond the Standard Model framework for cosmology and neutrino masses could arise by studying these interrelations.
