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 M −5R , 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.

For a high scale seesaw model where N \(\overline N \) oscillation is observable, see K S Babu and R N Mohapatra, Phys. Lett. B518, 269 (2001). In this model however, the lightest SUSY particle, the neutralino is unstable and cannot be a dark matter candidate. Also leptogenesis cannot explain the origin of matter, since fast ΔB=2 interactions erase any baryons generated via this mechanism
