摘要：

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