摘要：
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 414 fb(-1) of data that corresponds to 449 x 10(6) B (B) over bar pairs, which were taken on the Y(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(B-0 -> p (p) over bar) < 1.1 x 10(-7), B(B-0 -> Lambda(Lambda) over bar) < 3.2 x 10(-7), and B(B+-> p (Lambda) over bar) < 3.2 x 10(-7).
