We use 772 × 106 BB meson pairs collected at the ?ð4SÞ resonance with the Belle detector to measure the branching fraction for B ? Xs?. Our measurement uses a sum-of-exclusives approach in which 38 of the hadronic final states with strangeness equal to þ1, denoted by Xs, are reconstructed. The inclusive branching fraction for MXs
