Search for the rare decay B-0 ->tau(+)tau(-) at BABAR

We present the results of a search for the decay B-0 ->tau(+)tau(-) in a data sample of (232 +/- 3)x10(6) Upsilon(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 ->tau(+)tau(-))< 4.1x10(-3) at the 90% confidence level

Search for the Rare Decay B0→τ+τ- at BABAR

We present the results of a search for the decay B0→τ+τ- in a data sample of (232±3)×106 Υ(4S)→BB̅ 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(B0→τ+τ-)<4.1×10-3 at the 90% confidence level
