Abstract

We have measured the branching fraction of the inclusive radiative B meson decay B → X_sγ to be Br(B → X_sγ) = (3.36 ± 0.53(stat) ± 0.42(sys)_-0.54 ^+0.54(th)) × 10^-4. The result is based on a sample of 6.07 × 10⁶ B B̄ events collected at the γ(4S) resonance with the Belle detector at the KEKB asymmetric e⁺e^- storage ring.
