Studies of B decays to Charmonium at BABAR
نویسنده
چکیده
Using 22.7M BB events recorded by the BaBar detector, the inclusive branching ratios for the production of J/ψ , ψ(2S) and χc in B decays are presented. Combining the charmonium state with a K± , K, K∗± , K∗0 or π, B decays are reconstructed exclusively and their branching fractions are determined. A preliminary study is also presented for the B → ηcK decay mode.

Measurements of sin 2 β at B A B AR with charmonium and penguin decays
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 کاملExotic/charmonium Hadron Spectroscopy at Belle and Babar
A brief review of experimental results on charmonium and charmonium-like hadron spectroscopy at B-factories is presented. A special focus is put on recent results of η c and η c (2S) study, X(3872) radiative decays, ωJ/ψ final state study and search for charmonium production in radiative Υ decays.
متن کاملStudy 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...
متن کاملHadronic B Decays at BABAR
The BABAR collaboration has performed a number of measurements on hadronic B decays to charmonium and open charm mesons. Preliminary results based on a sample of nearly 23 million BB pairs, collected between October 1999 and October 2000, are reviewed. These include measurements of exclusive branching fractions and ratios of branching fractions, as well as angular distributions.
