摘要：

In the most general R-parity violating model, including both bilinear and trilinear terms, the sneutrino receives a vacuum expectation value [<(nu)over tilde>]. We investigate the constraints on [<(nu)over tilde>] following a basis independent approach, highlighting the relations between the three most popular bases. We study the prediction for the tau neutrino mass which follows from the minimization of the scalar potential in a SUGRA model with universality of the soft parameters at the GUT scale. Finally we show that the tau neutrino mass controls the R-parity violating effects both in the fermionic and scalar sectors, [S0556-2821(94)00815-2].
