We present the result of a search for the charmless two-body baryonic decay B0→p¯p in a sample of 88 million Υ(4S)→B¯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 …
