Fits to Moment Measurements from B->Xc lv and B-> Xs gamma Decays using Heavy Quark Expansions in the Kinetic Scheme

We present a fit to moment measurements of inclusive distributions in B->Xc lv and B->Xs gamma decays to extract values for the CKM matrix element |Vcb|, the b- and c- quark masses, and higher order parameters that appear in the Heavy Quark Expansion. The fit is carried out using theoretical c...

description We present a fit to moment measurements of inclusive distributions in B->Xc lv and B->Xs gamma decays to extract values for the CKM matrix element |Vcb|, 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 where correlation matrices have been published. We also derive values for the heavy quark distribution function parameters $m_b$ and $\mu_{\pi}^2$ in different theoretical schemes that can be used as input for the evaluation of the associated theory error on |Vub|.
