We present the result of a search for the charmless two-body baryonic decay B-0-->p(p) over bar in a sample of 88 million Y(4S)-->B(B) over bar decays collected by the BABAR detector at the SLAC PEP-II asymmetric-energy B Factory. We use Cherenkov radiation to identify protons cleanly, and determine the signal yield with a maximum-likelihood fit technique using kinematic and topological information. We find no evidence for a signal and place a 90% confidence-level upper limit of B(B-0--> <p(p)over bar >)<2.7x10(-7).

Abstract

We present the result of a search for the charmless two-body baryonic decay B-0-->p(p) over bar in a sample of 88 million Y(4S)-->B(B) over bar decays collected by the BABAR detector at the SLAC PEP-II asymmetric-energy B Factory. We use Cherenkov radiation to identify protons cleanly, and determine the signal yield with a maximum-likelihood fit technique using kinematic and topological information. We find no evidence for a signal and place a 90% confidence-level upper limit of B(B-0--> )<2.7x10(-7).
