Abstract

We present the results of a search for the decay B^0→τ^+τ^- in a data sample of (232±3)×10^6 Υ(4S)→BB decays using the BABAR detector. Certain extensions of the standard model predict measurable levels of this otherwise rare decay. We reconstruct fully one neutral B meson and seek evidence for the signal decay in the rest of the event. We find no evidence for signal events and obtain B(B^0→τ^+τ^-)<4.1×10^(-3) at the 90% confidence level.
