Search for Lepton Flavor Violating Decays tau^- --> l^-Ks^0 with the BABAR Experiment

Creators

Abstract

A search for the lepton flavor violating decays τ^- → l^- K^0_S (l = e or µ) has been performed using a data sample corresponding to an integrated luminosity of 469 fb-1, collected with the BABAR detector at the SLAC PEP-II e^+e^- asymmetric energy collider. No statistically significant signal has been observed in either channel and the estimated upper limits on branching fractions are B(τ^- → e^- K^0_S) < 3.3 × 10^(-8) and B(τ^- → µ^- K^0_S) < 4.0 × 10^(-8) at 90% confidence level.

We are grateful for the extraordinary contributions of our PEP-II colleagues in achieving the excellent luminosity and machine conditions that have made this work possible. The success of this project also relies critically on the expertise and dedication of the computing organizations that support BABAR. The collaborating institutions wish to thank SLAC for its support and the kind hospitality extended to them.
