Determination of |Vcb| and Related Results from BABAR
Abstract
The CKM matrix element amplitude |Vcb| was determined using the data collected by the BABAR detector. The partial branching fraction, lepton-energy moments, and hadron-mass moments were measured in inclusive semileptonic decays B -> Xc l nu. A global fit to a Heavy-Quark-Expansion calculation allowed precise determination of |Vcb|, mb, mc, B(B -> Xc l nu) and four non-perturbative parameters.
