Abstract.

We use the constituent quark model (CQM) to describe CDF data on double parton cross section and HERA data on the \(J / \Psi\) ratio cross section of elastic and inelastic diffractive productions. Our estimate shows that the radius of the constituent quark turns out to be rather small, \(R^2_{quark} \approx 0.1\) GeV-2, in accordance with the assumption on which CQM is based.
