Fit to moments of inclusive $B \to X_{c}l\overline{\nu}$ and $B \to X_{s}\gamma$ decay distributions using heavy quark expansions in the kinetic scheme

We present a fit to measured moments of inclusive distributions in Brightward arrowX/sub c/script lnumacron and Brightward arrowX/sub s /gamma decays to extract values for the Cabibbo-Kobayashi-Maskawa (CKM) matrix element |V/sub cb/|, the b- and c-quark masses, and higher-order parameters that appe...

description We present a fit to measured moments of inclusive distributions in Brightward arrowX/sub c/script lnumacron and Brightward arrowX/sub s /gamma decays to extract values for the Cabibbo-Kobayashi-Maskawa (CKM) matrix element |V/sub cb/|, the b- and c-quark masses, and higher-order parameters that appear in the heavy quark expansion. The fit is carried out using theoretical calculations in the kinetic scheme and includes moment measurements of the BABAR, Belle, CDF, CLEO, and DELPHI collaborations for which correlation matrices have been published. We find |V/sub cb/|=(41.96±0.23/sub exp/±0.35/sub HQErespectively. We also derive values for the heavy quark distribution function parameters m/sub b/ and mu/sub pi//sup 2/ in different theoretical schemes that can be used as input for the determination of |V/sub ub/|.
