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 339 fb − 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.
