Hadronic B Decays to Charm from Cleo
نویسنده
چکیده
Recent results include the measurement of B → D(∗)π+π−π−πo decays, with rates of ∼1.8%, observation of a significant ωπ substructure that appears to result from the decay of the ρ resonance, whose mass and width we determine as 1418 MeV and 382 MeV, respectively. Using B to charmonium decays we find that the B fraction in Υ(4S) decays is nearly half, that the CP asymmetries in J/ψK and ψK are small, and we also report on the first observation of B → ηcK.

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...
متن کاملHadronic Charm Decays in Cleo
We present several results on hadronic D meson decays. We report on results from the scan of the energy region from 3970 MeV to 4260 MeV, which was used to determine an optimal energy to carry out the Ds physics program of CLEO-c. Improved measurements of inclusive and exclusive D and Ds branching fractions are presented. We also show results on Dalitz analyses of D+ → π+π−π+ using CLEO-c data ...
متن کاملDetermination of Charm Hadronic Branching Ratios and New Modes
Precise measurements of the absolute branching fractions for D and Ds meson decays are important as they serve to normalize most B and Bs decays as well as many charm decays. Recent measurements from CLEO-c, BABAR, and Belle for the measurements of the absolute hadronic branching fractions of D and Ds mesons are presented here. Results from the CLEO-c experiment at the Cornell Electron Positron...

A selection of recent results on hadronic charm and beauty decays from the CLEO experiment are presented. We report preliminary evidence for the existence of final state interactions inB decays and the first observation of the decayB → DD with a branching fraction of (6.2 −2.9±1.0)×10 . We also present preliminary results on the first observation of the broad, J = 1, charmed meson resonance wit...
