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