Abstract

We report on a new search for two-body baryonic decays of the B meson. Improved sensitivity compared to previous Belle results is obtained from 414fb-1 of data that corresponds to 449×106 BB̄ pairs, which were taken on the Υ(4S) resonance and collected with the Belle detector at the KEKB e+e- collider. No significant signals are observed and we set the 90% confidence level upper limits: B(B0→pp̄)<1.1×10-7, B(B0→Λ Λ̄)<3.2×10-7, and B(B+→pΛ̄)<3. 2×10-7.
