Hadron Physics
Overview talk
When quarks were first discovered, it was widely considered that the age-old quest for finding the basic constituents of matter was finally over. All matter is comprised of hadrons & point-like leptons, and the hadrons, in turn, are made of quarks: three quarks form a baryon and a quark-antiquark pair forms a meson. However, developments during the intervening forty years indicate that...

The PAX collaboration has recently proposed to use an internal polarized hydrogen storage cell gas target in the Antiproton Decelerator ring (AD) of CERN to determine for the first time the two total spin–dependent pbar-p cross sections σ1 and σ2 at antiproton beam energies in the range from 50 to 450 MeV [1]. The data to be obtained are of interest in itself for the general theory of pbar-p...

Hadron Physics
Invited contribution
After an introduction to QCD and the concept of effective theories I will present some general considerations how to decide if a given hadron has a dominant hadronic substructure ("hadron molecule", dynamically generated state). I will select two examples, one from the sector of charmed mesons and one from the sector of light mesons, to illustrate these ideas.

At high energies the strong force is well described using quarks and gluons as degrees of freedom, while at lower energies hadronic degrees of freedom are more adequate. The PANDA energy regime is in the transition region between these two descriptions. Pbarp ->YbarY is a good reaction to test models based on these two alternative viewpoints. The weak decay of the hyperons gives direct access...

Hadron Physics
Contributed talk
The production of the charmed masons in ep collisions at HERA was studied using a life time tag with the ZEUS detector at HERA. New results on D meson production at HERA have been presented. Combinatorial background to the D-meson signals is reduced by using the ZEUS microvertex detector to reconstruct displaced secondary vertices. Production cross sections are compared with the predictions...

Hadron Physics
Invited contribution
Selected topics in strangeness nuclear physics are reviewed. The discussion involves hyperon-nucleus interactions, few-body systems with hyperons, spectroscopy of Lambda hypernuclei, double- and multi-strangeness baryonic systems. We also briefly report on the study of antikaon-nucleus dynamics in the quest for kaonic nuclei.
