Abstract
We report the first observation of the charmless hyperonic B decay, B-0-->p (&ULambda;) over bar pi(-), using a 78 fb(-1) data sample recorded on the Y(4S) resonance with the Belle detector at KEKB. The measured branching fraction is B(B-0-->p (&ULambda;) over bar pi(-))=(3.97(-0.80)(+1.00)+/-0.56)x10(-6). Searches for B-0-->p (&ULambda;) over barK(-) and p (&USigma;) over bar (0)pi(-) yield no significant signals and we set 90% confidence-level upper limits of B(B-0-->p (&ULambda;) over barK(-))<8.2x10(-7) and B(B-0-->p (&USigma;) over bar (0)pi(-))<3.8x10(-6).
