High Energy Physics - Experiment 2019-08-13 v1

Abstract

Presented are selected results of semileptonic B decays at BaBar. Two measurements of the Cabibbo-Kobayashi-Maskawa matrix element Vcb|V_{cb}| are reported. One using moments of the hadronic-mass spectrum in inclusive BˉXcνˉ\bar{B} \to X_{c} \ell^{-} \bar{\nu} decays, and the other, exclusive BˉDνˉ\bar{B} \to D \ell^- \bar{\nu}_{\ell} decays. These results are based on data samples of 232 (inclusive BˉXcνˉ\bar{B} \to X_{c} \ell^{-} \bar{\nu}) and 460 (exclusive \varBDνˉ\var{B} \to D \ell^- \bar{\nu}_{\ell}) million Υ(4S)BBˉ\Upsilon(4S) \to B\bar{B} decays, recorded by the BaBarBaBar detector at the PEP-II e+ee^+e^--storage rings. Semileptonic B decays are identified by requiring a lepton (ee or μ\mu) in events tagged with a full reconstruction of one of the B mesons in the BBˉB\bar{B} pair.
