Why is the decay ##\tau^{-} \rightarrow \mu^+ + \mu^- + \mu^-## not allowed?
Charge, lepton number are conserved. I have a feeling it is something really basic. I'm thinking in weak interactions you only go from a ##l^- \rightarrow \nu_{l}## and not 'hop' from one muon to another non-neutrino muon.
