摘要：

Supersymmetric theories violating R-parity allow a sneutrino VEV, which mixes neutrinos with neutralinos (χ0), and charged leptons with charginos (χ-). This gives neutrinos a mass, and causes such distinctive Z0 decays as Z0→vτχ 0 and Z0→τ+χ-, where χ0 and χ- subsequently decay. We place limits on these branching ratios from current neutrino mass limits. © 1990.
