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.
