  "abstract": "It has recently been shown that by extending the minimal standard model to include a right-handed partner to $\\nu_\\tau$, it is possible to gauge the $B - 3 L_\\tau$ quantum number consistently. If we add two scalar triplets, one trivial ($\\xi_1$) and one nontrivial ($\\xi_2$) under $B - 3 L_\\tau$, it is possible also to have desirable neutrino masses and mixing for neutrino oscillations. At the same time, a lepton asymmetry can be generated in the early universe through the novel mechanism of the decay of the heavier $\\xi_1$ into the lighter $\\xi_2$ plus a neutral singlet ($\\zeta^0$). This lepton asymmetry then gets converted into a baryon asymmetry at the electroweak phase transition.",
