Search for the Rare DecayB0→τ+τ−atBABAR

We present the results of a search for the decay B{sup 0}{yields}{tau}{sup +}{tau}{sup -} in a data sample of (232{+-}3)x10{sup 6} {upsilon}(4S){yields}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{sup 0}{yields}{tau}{sup +}{tau}{sup -})
