We consider the sneutrino resonance reaction l^+ l^- -> sneutrino -> tau^+tau^- in the MSSM without R-parity. We introduce new CP-violating andCP-conserving tau-spin asymmetries which are generated already at thetree-level if there is sneutrino - sneutrino-bar mixing and that are forbiddenin the SM. It is remarkable that these spin asymmetries can reach ~75% aroundresonance for a sneutrino mass splitting of \Delta m ~ \Gamma and ~10% for asplitting as low as \Delta m ~ 0.1\Gamma, where \Gamma is the sneutrino width.We show that they are easily detectable already at LEP2 so long as the beamenergy is within ~10 GeV range around the muon-sneutrino masses and maytherefore serve as extremely powerful probes of sneutrino mixing phenomena.Comment: 12 pages, plain latex, 3 figures embadded in the text using epsfi
