    • Abstract

       

      See-saw mechanism has been a dominant paradigm in the discussion of neutrino masses. We discuss how this idea can be tested via a baryon number violating process such as N-$$\overline N $$ oscillation. Since the expected see-saw scale is high and the N-$$\overline N $$ amplitude goes like MR−5, one might think that this process is not observable in realistic see-saw models for neutrino masses. In this talk I show that in supersymmetric models, the above conclusion is circumvented leading to an enhanced and observable rate for N$$\overline N $$ oscillation. I also discuss a new mechanism for baryogenesis in generic models for neutron-anti-neutron oscillation.
