The branching fraction for the inclusive decay Β→Xsℓ+ℓ- was measured. A data sample collected at the Υ(4S) resonance with the Bell detector at the KEKB e+e- asymmetric-energy collider was used. Overall, the results are in agreement with the standard model (SM) expectations and can be used to constrain extensions of the SM.
