This volume reviews recent advances in both theoretical and experimental studies in the field of medium energy physics. The following topics are covered: hadronic structures; hadron-hadron interactions; QCD and its model theory; meson physics; medium and high energy lepton-nucleus interactions; weak interaction and double-βdecay in nuclei; p-p and p-nucleus interactions; systems with strangeness and hypernuclei; and high energy p-A and A-A collisions and QGP.
