B Xs + - at Belle
Abstract
Evidence for the inclusive B Xs + - decay has been presented based on 41.8 fb-1 data sample collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric e+e- collider. A preliminary result for the branching fraction is B(B Xs + -) = (7.1 +- 1.6 (stat.) + 1.4 - 1.2(syst.)) × 10-6.
