Outstanding Issues in Hadron PhysicsOutstanding Issues in Hadron Physics
• How are hadrons (baryons and mesons) built from quarks and gluons?
• Can we quantitatively account for the confinement of quarks and gluons inside hadrons?
• What determines the nucleon mass?
e.g., nucleon = complex many-body system of quarks and gluons
• J/ spectroscopy confinement
• glueballs (ggg) and hybrids (ccg)
• hidden and open charm mesons in nuclei
• hypernuclei

Further possibilities:
• Inverted Deeply Virtual Compton Scattering
• CP-violation (D/-sector)
• fundamental symmetries; p in traps

• high beam quality by stochastic and electron cooling micro vertex trigger for D-meson physics
• high resolution spectroscopy with p-beams in formation experiments: E,Ebeam
• high yields in pp of gluonic excitations (glueballs, hybrids)
• event tagging by pairwise (particle, particle) production, e.g. pp

SummarySummary
Antiprotons in the HESR will ...
... provide a broad and challenging research program (cc), (ccg), (ggg), mD, A, IDVCS, CP, CPT
... allow GSI to play a leading role in exploring long distance (non-perturbative) QCD
... be an integral part of GSI's efforts to unravel all facets of the strong interaction and of hadronic matter (p, AA-collisions, exotic nuclei)
