Measurement of the branching fraction with a sum of exclusive decays
Abstract
We use 772 × 106 BB-bar meson pairs collected at the Υ(4S) resonance with the Belle detector to measure the branching fraction for B-bar → Xsγ. Our measurement uses a sum-of-exclusives approach in which 38 of the hadronic final states with strangeness equal to +1, 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 B(B-bar → Xsγ)=(3.51±0.17±0.33) × 10–4, where the first uncertainty is statistical and the second is systematic.
