B to charmonium - mini-summary
نویسنده
چکیده
I summarize recent experimental results on B to charmonium decays. Decays of B meson to final states that include charmonium states play an important role in the study of CP violation at B-factories. The decay modes BCP → J/ψKS, ψ(2S)KS, χc1KS, ηcKS, J/ψKL and J/ψK (K → KSπ ) have been used for sin2φ1 measurements [1] [2] [3] [4] [5]. These two-body decay modes are dominated by the color suppressed b → c transition. Other CP eigenstates of the neutral B meson, e.g. J/ψρ, may also be useful for the CP measurements. Meanwhile, the branching fractions for the B → charmonium decays can provide valuable information on their decay mechanism.

Charmonium at Bes and Cleo-c
This paper gives a short summary of some of the aspects of charmonium which can be addressed at BES and CLEO-c and other e + e − facilities. These topics include the spectroscopy of charmonium states, radiative transitions, e + e − widths, two-photon widths, hadron loop effects and open-flavor strong decays.
متن کاملCharmonium Production in High Energy Collisions
One motivation for studying the production of charmonium in high energy collisions is that these particles are among the simplest probes for heavy-ion collisions. In recent years, there have been significant developments in heavy quarkonium production, both in theory and in experiment. These developments may have important implications for the use of charmonium as a probe in heavy-ion collision...

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 کاملQcd Spectroscopy at Gsi: Exotica and Charmonia
In this talk I give a short summary of the basics of conventional and exotic meson spectroscopy, and consider in particular those issues in the charmonium and charmonium hybrid sectors which can be addressed by a future antiproton facility at GSI. 1 QCD and Confinement The QCD lagrangian describes the strong interaction in terms of the couplings between the elementary pointlike quark (antiquark...
