Title: Measurement of the B → Xsγ branching fraction with a sum of exclusive decays

Abstract

We use 772 × 106 BB meson pairs collected at the Yð4SÞ resonance with the Belle detector to measure the branching fraction for B → Xsγ. 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 < 2.8 GeV=c2, which corresponds to a minimum photon energy of 1.9 GeV, is measured to be BðB¯ → XsγÞ¼ð3.51 0.17 0.33Þ × 10 -4, where the first uncertainty is statistical and the second is systematic.
