Limits on τ lepton-flavor violating decays into three charged leptons
A search for the neutrinoless, lepton-flavor violating decay of the τ lepton into three charged leptons has been performed using an integrated luminosity of 468 fb − 1 collected with the BABAR detector at the PEP-II collider. In all six decay modes considered, the numbers of events found in data...

| Sumario: | A search for the neutrinoless, lepton-flavor violating decay of the τ lepton into three charged leptons has been performed using an integrated luminosity of 468 fb − 1 collected with the BABAR detector at the PEP-II collider. In all six decay modes considered, the numbers of events found in data are compatible with the background expectations. Upper limits on the branching fractions are set in the range ( 1.8 - 3.3 ) × 10 − 8 at 90% confidence level. |
