Transition from strong to perturbative QCD
Where does the dynamics of the q-q-bar interactions make a transition from the strong (confinement) to the perturbative (QED-like) regime?
Experiments
The CEBAF program that is directly relevant to this question is the determination of the pion form factor. First results from a 4 GeV run in Hall C are available, an extension to higher momentum transfer has just been completed. Final resolution of the issue will have to await the 12 GeV Upgrade.
