Study of high-multiplicity τ decays and a search for second-class currents at BaBar
We present measurements of the branching fractions of high-multiplicity τ decay modes and a search for τ second class current decays using a sample of 430 million τ lepton pairs, corresponding to an integrated luminosity of 468 fb-1, collected with the BaBar detector at the PEP-II asymmetric-energy storage rings at SLAC.
