Abstract

Description

The CLEO Collaboration has extracted improved values of |V_cb| and |V_ub| from measurements of exclusive and inclusive decays of B mesons. The measurement of B -> D* ell nu at zero recoil combined with the predicted form factor F_D*(w_min) yields |V_cb|. The photon energy spectrum in b -> s gamma and the hadronic recoil mass spectrum in B -> X_c ell nu determine non-perturbative HQET parameters used with inclusive b -> c and b -> u rates to obtain |V_cb| and |V_ub|.
