Search for Lepton Flavor Violating Decays τ±→ℓ±π0, ℓ±η, ℓ±η'
Abstract
A search for lepton flavor violating decays of the τ lepton to a lighter mass lepton and a pseudoscalar meson has been performed using 339fb-1 of e+e- annihilation data collected at a center-of-mass energy near 10.58 GeV by the BABAR detector at the SLAC PEP-II storage ring. No evidence of a signal has been found, and upper limits on the branching fractions are set at the 10-7 level.
