Description
Hadron Physics is the physics of strongly interacting systems. In the past thirty years Quantum Chromo Dynamics (QCD) has evolved as the theory of strong interactions, which describes the interaction among quarks through the exchange of gluons. QCD is believed to be well understood at short distance scales, but this is not longer the case as soon the as the basic quark-gluon coupling is not weak anymore. This region of strong QCD is governed by non-perturbative phenomena leading e.g. to the formations of hadrons. The underlying processes like confinement and chiral symmetry breaking are however not very well understood. This presents a profound intellectual challenge for both experimentalists and theorists. Experiments with antiprotons have proven to be a rich source of information in hadron physics. With the new FAIR facility together with the proposed PANDA experiment, utilizing antiproton annihilations, the physics of strange and charm quarks will be accessible for hadron physics, which received very recently additional attention due to the observation of unexpected narrow states by the BELLE and BaBar collaborations. Indeed, it will be shown that both, e+e- results and antiproton results complement each other in an ideal way.
