High Energy Physics - Experiment 2019-08-14 v1

Abstract

Evidence for the inclusive BXs+B \to X_s \ell^+ \ell^- 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(BXs+B \to X_s \ell^+ \ell^-) = (7.1 +- 1.6 (stat.) + 1.4 - 1.2(syst.)) \times 10^-6.
