Comments and Questions
- Measuring the differential cross section of charmonium production from threshold to O(~100GeV) establishes if there is a common production mechanism across the entire energy range. If this the case one can use the high energy phenomenology and QCD arguments to evaluate the gluon form factors of the nucleon. This would be a discovery of a new QCD phenomenon, since what is known so far from e.g. from light vector mesons is that threshold and high energy production are driven by very different mechanisms (e.g. production of N*’s vs diffraction).
