There is no doubt that the calculation of a strongly interacting process is a very difficult assignment. However, even without doing such calculations one can apply fundamental laws of physics and derive conclusion pertaining to hadronic structure. Below are a few points that are relevant to the...
Well, the increase within the curve is small, but compared to what one would expect it is not small. If one interprets "asymptotic freedom" as "vanishing interaction at high energy" then a decrease like in the coulomb range should be expected. So we have something here what QCD can't explain?
Hi!
On page 12 of http://pdg.lbl.gov/2009/reviews/rpp2009-rev-cross-section-plots.pdf one can see the total cross section increasing beyond a certain treshold. At higher energy protons (and their quarks) have a shorter wave length and so they can become closer an closer and the strong force...
