Radiative B Meson Decay
Yutaka Ushiroda
Abstract
We studied radiative B meson decays with the Belle detector. We measured the following branching fractions; Br(B->K*0(892)γ) = (49.6 6.7 4.5) x 10-6, Br(B->K*+(892)γ) = (38.9 9.3 4.1) x 10-6, Br(B->Xsγ) = (3.39 0.53 0.42 +0.51-0.55) x 10-4. We also set an upper limit for B -> ργas Br(B->ργ)/Br(B->K*(892)γ) < 0.19 at 90% confidence level.
