摘要
Four B+→J/ψpΛ̄ candidates in a data set of (88.9±1.0) X 106 Y(4S) decays were observed. The probability of the expected charged B background 0.21±0.14 events, producing ≥4 events was 2.5X10-4. The branching fraction is (12-6 +9)X10-6, where the uncertainty includes both statistical and systematic components.
