Many models for physics beyond the Standard Model predict lepton-flavour violating decays of charged leptons at a level which may become observable very soon. In the present paper we investigate the decays of a Tau into three charged leptons in a generic way, based on effective-field-theory methods, where the relevant operators are classified according to their chirality structure. We work out the decay distributions and discuss phenomenological implications.

    Belle II sets upper limits between 1.3 and 2.5 times 10 to the minus 8 on branching fractions for four tau to e l l decay modes at 90 percent confidence level, the most stringent to date for four modes.
