Hadron Spectroscopy

1 Light Hadron Spectroscopy ∗

Recent developments in calculations of the light hadron spectrum are reviewed. Particular emphasis is placed on discussion of to what extent the quenched spectrum agrees with experiment. Recent progress, both for quenched and full QCD, in reducing scaling violation with the use of improved actions is presented.

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...

Light hadron spectroscopy

Calculation of the hadron spectrum has been a central goal of Lattice QCD for 20 years. A precision calculation of the hadron spectrum would be a validation of QCD, and a validation of Lattice QCD as a calculational technique. It would give us con dence when we apply lattice QCD to calculating other quantities. In addition we would be able to clarify the nature of observed hadrons and predict w...

Hadron Spectroscopy at Hera

on behalf of the ZEUS and H1 Collaborations Inclusive photoproduction cross-sections of the neutral mesons η, ρ 0 , f 0 (980) and f 2 (1270) have been measured by H1 and compared to the photoproduction of π + in ep collisions at HERA. Also, inclusive K 0 s K 0 s production and evidence for a narrow baryonic state decaying to K 0 s p have been observed by ZEUS at HERA.
