Measurement of /V(sub cb) and the Form-Factor Slope for overbar B Yields Dl(sub -)Nu(sub l) Decays on the Recoil of Fully Reconstructed B Mesons

摘要

We present a measurement of the CKM matrix element 'V(sub cb)' and the form-factor slope (rho)(sup 2) for (bar B) (yields) D(ell)(sup -) (bar (nu))(sub (ell)) decays based on 417 fb(sup -1) of data collected at the (Upsilon)(4S) resonance with the BABAR detector. The semileptonic decays are selected in B(bar B) events in which the hadronic decay of the second B meson is fully reconstructed.
