Book excerpt: The authors report updates on two analyses of inclusive semileptonic B decays based on a dataset of 89 million B{bar B} events recorded with the BABAR detector at the?(4S) resonance. Events are selected by fully reconstructing the decay of one B meson and identifying a charged lepton from the decay of the other {bar B} meson. IN the first analysis, the measurement of the first and second moment of the hadronic mass distribution in Cabibbo-favored {bar B} → X{sub c}l{bar {nu}} decays allows for the determination of the nonperturbative parameters {bar {Lambda}} and?1 of Heavy Quark Effective Theory (HQET) and.

Available in PDF, EPUB and Kindle. Book excerpt: We report a measurement of the first four moments of the hadronic mass distribution in [bar B] [yields] X[sub c][ell][sup -] [bar [nu]] decays. The measurements are based on 89 million [Upsilon](4S) [yields] B[bar B] events where the hadronic decay of one of the B mesons is fully reconstructed and a charged lepton from the decay of the other B meson is identified. The moments are presented for minimum lepton momenta ranging from 0.9 to 1.6 GeV in the B rest frame. It is expected that such measurements will lead to improved determinations of V[sub cb] and V[sub ub].
