Inclusive decays of B mesons to charmonium.
نویسندگان
چکیده
We have used the CLEO-II detector at the Cornell Electron Storage Ring to study the inclusive production of charmonium mesons in a sample of 2.15 million BB events. We nd inclusive branching fractions of (1.130.040.06)% for B!J==X, (0.340.040.03)% for B! 0 X, and (0.400.060.04)% for B! c1 X. We also nd some evidence for the inclusive production of c2. An upper limit for the branching fraction of the inclusive decay B! c X of 1.0% at 90% conndence level is presented. Momentum spectra for inclusive J== and 0 production are presented. These measurements are compared to theoretical calculations.

Study of Charmonium Production and Electroweak Penguins with BABAR
We report measurements of charmonium resonances (J/ψ, ψ(2S), χc1) using about 25 fb −1 of data collected by the BABAR detector around the Υ(4S) resonance. We present measurements of inclusive charmonium production of charmonium in B decays and from the continuum, as well as exclusive branching ratios of B mesons into charmonium final states. We present also a measurement of the B → Kγ branching...

Measurements of sin 2β at BABAR with charmonium and penguin decays. Abstract This article summarises measurements of time-dependent CP asymmetries in decays of neutral B mesons to charmonium, open-charm and gluonic penguin-dominated charmless final states. Unless otherwise stated, these measurements are based on a sample of approximately 230 million Υ (4S)→ BB decays collected by the BABAR dete...
متن کاملInclusive J / ψ and ψ ( 2 S ) Production from B Decay in pp̄ Collisions
Using information on B-meson fragmentation functions from CERN LEP 1 and adopting the nonrelativistic QCD factorization formalism proposed by Bodwin, Braaten, and Lepage, we predict the transverse-momentum distribution of J/ψ mesons originating from the inclusive decays of b hadrons produced in pp̄ collisions at the Fermilab Tevatron. We determine the relevant colour-octet charmonium matrix elem...
