Book Description
This conference covered recent developments, both experimental and theoretical, in the study of hadron spectroscopy. It focused primarily on the spectroscopy, properties, theories and models of: light-quark mesons, heavy-quark mesons and baryons, exotic states (glueballs and hybrid mesons), and future facilities for their continued study.Special features to note include: New results were presented on the ƒ0(1500) meson from the Crystal Barrel, OBELIX and GAMS collaborations, indicating that this state is now a clear candidate for the lowest 0++ glueball; The existence of the ξ(2230) was confirmed by new data from BES; A session on future facilities; New results on charmed mesons and on hadrons with b quarks were also presented.

Book Description
The arena of doubly and triply heavy baryons remains experimentally unexplored to a large extent. This has led to a great deal of theoretical effort being put forth in the calculation of mass spectra in this sector. Although the detection of such heavy particle states may lie beyond the reach of experiments for some time, it is interesting to compare results between lattice QCD computations and continuum theoretical models. Several recent lattice QCD calculations exist for both doubly and triply charmed as well as doubly and triply bottom baryons. In this work we present preliminary results from the first lattice calculation of the mass spectrum of doubly and triply heavy baryons including both charm and bottom quarks. The wide range of quark masses in these systems require that the various flavors of quarks be treated with different lattice actions. We use domain wall fermions for 2+1 flavors (up down and strange) of sea and valence quarks, a relativistic heavy quark action for the charm quarks, and non-relativistic QCD for the heavier bottom quarks. The calculation of the ground state spectrum is presented and compared to recent models.

Book Description
Due to an excellent mass resolution and a large amount of available data, the CDF experiment, located at the Tevatron proton-antiproton accelerator, allows the precise measurement of spectroscopic properties, like mass and decay width, of a variety of states. This was exploited to examine the first orbital excitations of the?{sub c} baryon, the resonances?{sub c}(2595) and?{sub c}(2625), in the decay channel?{sub c}?+?−, as well as the?{sub c} spin excitations?{sub c}(2455) and?{sub c}(2520) in its decays to?{sub c}+?− and?{sub c}+?− final states in a data sample corresponding to an integrated luminosity of 5.2 fb−1. We present measurements of the mass differences with respect to the?{sub c} and the decay widths of these states, using significantly higher statistics than previous experiments.
