Spectroscopy of Heavy Quarkonia
نویسنده
چکیده
In the last few years, the CLEO III experiment has recorded a large collection of data sets at the Υ(1S), Υ(2S), Υ(3S) and ψ(2S) resonances. Preliminary results of studies of these data sets are shown here, which include the observation of a new Υ(1D) state, as well as several hadronic and radiative transitions of Υ and ψ(2S) states. In addition, precision branching ratio measurements of charmonium and bottomonium states and recent developments involving the ηc(2S) and X(3872) states are presented.

Heavy Quarkonia
Recent experimental results on heavy quarkonia spectroscopy and decays are reviewed. In particular, new results are discussed on charmonium spin singlet states, bottomonium D-states, photon and hadronic transitions from heavy quarkonium states, and the unexplained narrow X(3872) state.
متن کاملHeavy Quarkonia Spectroscopy and Decays
The experimental status of stable bound states made out of heavy quarks is reviewed. The need for a way to deal with the non-perturbative transitions involved calls for precision measurements on one hand, and for discovery of as yet undetected states to confirm predictions on the other. In this article, recent experimental contributions to heavy quarkonia spectroscopy and decay will be reviewed...

This report is the result of the collaboration and research effort of the Quarkonium Working Group over the last three years. It provides a comprehensive overview of the state of the art in heavy-quarkonium theory and experiment, covering quarkonium spectroscopy, decay, and production, the determination of QCD parameters from quarkonium observables, quarkonia in media, and the effects on quarko...
متن کاملHeavy Quark-meson Mass Gap from Spectroscopy
Using a quite accurate flavour-independence of nS-level mass differences in heavy quarkonia and a corresponding quasiclassical expression for the heavy quark binding energy, one shows that experimental data on masses of mesons with heavy quarks allow one to make the estimate ¯ Λ = 0.63 ± 0.03 GeV.

Studying the production or decay processes of heavy quarkonia (the bound state of heavy quark-antiquark) is a powerful tool to test our understanding of strong interaction dynamics and QCD theory. Fragmentation is the dominant production mechanism for heavy quarkonia with large transverse momentum. The fragmentation refers to the production process of a parton with high transverse momentum whic...
