A search for the nonconservation of lepton flavor in the decay τ±→e±γ has been performed with 2.07×108 e+e−→τ+τ− events collected by the BABAR detector at the SLAC PEP II storage ring at a center-of-mass energy near 10.58 GeV. We find no evidence for a signal and set an upper limit on the branching ratio of ℬ(τ±→e±γ)<1.1×10−7 at 90% confidence level.

Abstract

A search for the nonconservation of lepton flavor in the decay τ±→e±γ has been performed with 2.07×108 e+e−→τ+τ− events collected by the BABAR detector at the SLAC PEP II storage ring at a center-of-mass energy near 10.58 GeV. We find no evidence for a signal and set an upper limit on the branching ratio of ℬ(τ±→e±γ)<1.1×10−7 at 90% confidence level.
