Direct measurements of charmed-D-meson hadronic branching fractions.
A new technique is applied to data collected at the +(3770) resonance to derive charmed D meson branching fractions without relying on the measurement of D production cross sections. Measurements are presented for three decay modes of the Do (K-n+, K-?r-w+r+ and K-7r+r ") and four decay modes of the D+ (K-7r+rr+, K-x+r+~~, Kt?r+ and Kfr+7r "). The resulting branching fractions are significantly...
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...
متن کاملB Decays to D
The e + e − annihilation data recorded with the BABAR detector has been used to study B 0 decays to D (*)+ s and D * − mesons. The production fraction of inclusive D (*)+ s and the corresponding momentum spectra have been determined. Exclusive decays B 0 → D * − D (*)+ s have been identified with a partial reconstruction technique and their branching ratios have been measured. Fully reconstruct...
متن کامل00 4 FIRST RESULTS FROM CLEO - c at E CM = Ψ ( 3770 )
The CLEO-c detector at CESR has begun to collect large data sets of e + e − → c¯ c events in the center-of-mass energy range √ s = 3 − 5 GeV that will greatly enhance the size of the world's data sets of events produced at charm threshold. Preliminary results for the pseudoscalar decay constant f D + and absolute D-meson hadronic branching fractions from an initial integrated luminosity L = 57 ...
