%0 Journal Article %T How Neutrinos Get Mass and What Other Things May Happen Besides Oscillations %A Ernest Ma %J Physics %D 2000 %I arXiv %R 10.1007/s12043-000-0098-x %X In this talk I address the theoretical issue of what new physics is required to make $m_\nu \neq 0$. I then discuss what other things may happen besides neutrino oscillations. In particular I consider a possible new scenario of leptogenesis in R parity nonconserving supersymmetry. %U http://arxiv.org/abs/hep-ph/0001246v1
