A review of heavy-heavy spectroscopy

A review of heavy-heavy spectroscopy

Calculations of the heavy-heavy spectrum present a good opportunity for precision tests of QCD using lattice techniques. All methods make use of a non-relativistic expansion of the action and its systematic improvement to remove lattice artefacts. There was convincing demonstration this year that these methods work and that the associated perturbation theory is well-behaved. Comparison to exper...

Review of Heavy Hadron Spectroscopy

The status of some of the recently discovered heavy hadrons is presented.

Spectroscopy of Heavy Quarkonia

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 charmo...

Heavy Hadron Spectroscopy

After having played a major role in the foundation of QCD, heavy hadron spectroscopy has witnessed in the last years a renewal of interest led by the many new data coming from the B factories, CLEO and the Tevatron and by the progress made in the theoretical methods. I will summarize the former and mostly focus on the latter. Much of the theoretical progress in the physics of heavy hadrons come...
