摘要：

I show that the equality of the rates for τ→μ++neutrinos and τ+→e++neutrinos does not necessarily exclude the possibility that τ+ is a paraelectron with the same lepton number as e-, but it does require some rather unconventional decay matrix element. Different matrix elements predict different values for Michel ρ parameters and daughter lepton helicities; tests for the paraelectron assignment occur in e+e- annihilation. © 1978 The American Physical Society.
