B Meson Decays: Recent Results from Cleo

نویسنده

چکیده

The CLEO Collaboration has extracted improved values of |Vcb| and |Vub| from measurements of exclusive and inclusive decays of B mesons. The measurement of B → D l ν at zero recoil combined with the predicted form factor FD∗(wmin) yields |Vcb|. The photon energy spectrum in b → s γ and the hadronic recoil mass spectrum in B → Xc l ν determine non-perturbative HQET parameters used with inclusive b → c and b → u rates to obtain |Vcb| and |Vub|.

Charm Physics Results from CLEO The CLEO Collaboration

We present recent results in the charm sector from the CLEO Collaboration. The data used were collected by the CLEO II and III detectors at the Cornell Electron Storage Ring (CESR). Measurements of form factors and branching fractions in semileptonic decays of D-meson and charmed-baryons, searches for CP violation and rare decays, and Dalitz analyses of D-meson decays are discussed, as well as ...

Hadronic Decays of B Mesons

We review recent experimental results on hadronic decays and lifetimes of hadrons containing b and c quarks[1]. We discuss charm counting and the semileptonic branching fraction in B decays, the color suppressed amplitude in B decay, and the search for gluonic penguins in B decay. A complete picture of inclusive B decay is beginning to emerge from recent measurements by CLEO II and the LEP expe...
