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-
oscillation. Since the expected see-saw scale is high and the N-
amplitude goes like M
R
−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
oscillation. I also discuss a new mechanism for baryogenesis in generic models for neutron-anti-neutron oscillation. |
