- Abstract
- Using the previous Belle measurement of the inclusive photon energy in B -> X(s)gamma decays, we determine the first and second moments of this spectrum for minimum photon energies in the B meson rest frame ranging from 1.8 to 2.3 GeV. Combining these measurements with recent Belle data on the lepton energy and hadronic mass moments in B -> X(c)center dot nu decays, we perform fits to theoretical expressions derived in the 1S and kinetic mass schemes and extract the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element V(cb), the b-quark mass, and other nonperturbative parameters. In the 1S scheme analysis we find |V(cb)|=(41.56 +/- 0.68(fit)+/- 0.08(tau(B)))x10(-3) and m(b)(1S)=(4.723 +/- 0.055) GeV. In the kinetic scheme, we obtain |V(cb)|=(41.58 +/- 0.69(fit)+/- 0.08(tau(B))+/- 0.58(th))x10(-3) and m(b)(kin)=(4.543 +/- 0.075) GeV.
