• What is the three-dimensional distribution of
  charge, current and spin within the nucleon as
  well as within nuclei? This includes parton
  distribution functions (PDFs), form factors
  (especially at high-Q2), and generalized partons
  distributions (GPDs).
• What is the role of heavy flavors, especially
  strangeness, in systems composed primarily of
  light quarks?
• What is the spectrum of excited mesons and
  baryons? In particular, what is the spectrum of
  mesons containing explicit glue, including
  glueballs and exotic mesons? Where are the
  missing baryons''? Are there exotic baryons,
  such as pentaquarks?
• What role does QCD at its fundamental level of
  quarks and gluons play in determining the
  structure and properties of atomic nuclei?

• How does confinement work? What are the roles,
  if any, of monopoles, instantons, calorons,
  center vortices, or other classical QCD degrees
  of freedom?
• What are the shapes of hadrons? Do any of them
  have deformed intrinsic states like nuclei? If
  so, what physics drives the deformation?
• What is the role of diquarks in hadrons? Can one
  measure significant diquark correlations? How do
  diquarks arise from underlying interactions?
• To what extent can hadron-hadron interactions be
  understood directly from QCD? Can scattering
  lengths for experimentally known cases be
  calculated with sufficient accuracy to make
  experimentally unknown cases credible? What
  features of nuclear forces can be gleaned from
  the static interactions of heavy-light systems?
