Abstract
We have measured the branching fraction of the inclusive radiative B meson decay B -->X(s)gamma to be Br(B --> X(s)gamma) = (3.36 +/- 0.53(stat) +/- 0 .42(sys)(-0.54)(+0.50)(th)) x 10(-4). The result is based on a sample of 6. 07 x 10(6) B (B) over bar events collected at the gamma (4S) resonance with the Belie detector at the KEKB asymmetric e(+)e(-) storage ring.
