We report a measurement of the branching fraction and final-state asymmetry for the B¯ 0 ? K0
SK±p+_ decays. The analysis is based on a data sample of 711 fb-1 collected at the ?(4S) resonance with the Belle
detector at the KEKB asymmetric-energy e+e- collider. We obtain a branching fraction of (3.60+ _ 0.33 +_
0.15) × 10-6 and a final-state asymmetry of (-8.5+ _ 8.9+ _ 0.2)%, where the first uncertainties are
statistical and the second are systematic. Hints of peaking structures are found in the differential branching
fractions measured as functions of Dalitz variables.
