Semileptonic B Decays from CLEO
Karl M. Ecklund
Abstract
I report results in semileptonic decays of B mesons from the CLEO collaboration, with a focus on recent results. Results for exclusive reconstruction of B -> D* l nu, B -> D l nu and B -> rho l nu are given including the q2 dependence of the form factors. These results are used to measure |Vcb| and |Vub|. Two preliminary analyses using inclusive techniques measure the lepton momentum spectrum and hadronic recoil mass spectrum in B -> Xc l nu decays, showing promise for future precision measurements of |Vcb|.
