Abstract

We present the result of a search for the charmless two-body baryonic decay

B^{0} \to p \bar{p}

in a sample of 88 million

Υ (4 S) \to B \bar{B}

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} \to p \bar{p}) < 2.7 \times 10^{- 7} .
