Opis

Nowadays the realm of intermediate energy as a bridge between nuclear and particle physics attracts considerable interest. This volume surveys recent developments in the theory of quark correlations in hadronic matter and also informs about experimental findings. The main themes are: dynamicalsymmetries of heavy quarks, diquarks, weak interactions, hadron spectroscopyand quark models, chiral invariant quark forces, quark confinement and quarkaspects of hadronic interactions.
