Rare tau decays from B ABAR

The BABAR experiment has now completed data taking and with an integrated luminosity of 531 fb-1 of e+e-collision data has recorded some 480 million tau-pair events.Various studies of suppressed,rare and forbidden decays of the tau have been conducted,including searches for high-multiplicity decays,for second-class hadronic weak currents,and for lepton-flavour violation.
