Workshop JINR/BMBF18.Jan.05, H.O. Challenging problems in non-perturbative QCD Do glueballs (ggg) and hybrids (qqg) exist?  New experimental approach: antiproton beams up to 15 GeV/c Why are quarks confined within hadrons? How are hadrons constructed from their constituents? What is the relation of parton degrees of freedom and the low energy structure of hadrons? What is the origin of hadron masses? How are hadrons modified when embedded in nuclei?
