Evidence for the decay B0pp¯π0

Abstract

We report a search for the charmless baryonic decay B0pp¯π0 with a data sample corresponding to an integrated luminosity of 711fb1 containing (772±10)×106 BB¯ pairs. The data were collected by the Belle experiment running on the ϒ(4S) resonance at the KEKB e+e collider. We measure a branching fraction B(B0pp¯π0)=(5.0±1.8±0.6)×107, where the first uncertainty is statistical and the second is systematic. The signal has a significance of 3.1 standard deviations and constitutes the first evidence for this decay mode. We also search for the intermediate two-body decays B0Δ+p¯ and B0Δ¯p, and set an upper limit on the branching fraction, B(B0Δ+p¯)+B(B0Δ¯p)<1.6×106 at 90% confidence level.
