Search For Lepton Flavour Violation Lfv In Three Body Tau Decays At Babar

The results of searches for Lepton Flavour Violating (LFV) decays at the BaBar detector located on the PEP-II collider, using data collected at an ee− energy of 10.58 GeV, are presented. Upper limits at 90% Confidence Level (CL) are established in the range 1-3 x 10−7 for six [tau] 2!lll modes using 91.5 fb−1 of data and in the range 0.7-4.8 x 10−7 for fourteen [tau] 2!lhh modes using 221.4 fb−1 of data. The [tau] 2!lhh results are preliminary.
