Abstract
We use the constituent quark model (CQM) to describe CDF data on double parton cross section and HERA data on the J/ψ 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, Rquark2 ≈ 0.1 GeV-2, in accordance with the assumption on which CQM is based.
