Query: Testing Quantum Chromodynamics with Antiprotons   The antiproton storage ring HESR to be constructed at GSI will open up a new
range of perturbative and nonperturbative tests of QCD in exclusive and
inclusive reactions. I discuss 21 tests of QCD using antiproton beams which can
illuminate novel features of QCD. The proposed experiments include the
formation of exotic hadrons, measurements of timelike generalized parton
distributions, the production of charm at threshold, transversity measurements
in Drell-Yan reactions, and searches for single-spin asymmetries. The
interactions of antiprotons in nuclear targets will allow tests of exotic
nuclear phenomena such as color transparency, hidden color, reduced nuclear
amplitudes, and the non-universality of nuclear antishadowing. The AdS/CFT
correspondence of large $N_C$ supergravity theory in higher-dimensional anti-de
Sitter space with supersymmetric QCD in 4-dimensional space-time has important
implications for hadron phenomenology in the conformal limit, including the
nonperturbative derivation of counting rules for exclusive processes and the
behavior of structure functions at large $x_{bj}.$ String/gauge duality also
predicts the QCD power-law fall-off of light-front Fock-state hadronic
wavefunctions with arbitrary orbital angular momentum at high momentum
transfer. I also review recent work which shows that the diffractive component
of deep inelastic scattering, single spin asymmetries, as well as nuclear
shadowing and antishadowing, cannot be computed from the LFWFs of hadrons in
isolation.
