Query: Generelized parton distributions and the structure of the hadrons   The dependence of the hadron interaction on its structure is examined in the
framework of the generelized parton distributions (GPDs). The x dependence of
the GPDs is determined by the parton distribution functions (PDFs), which were
obtained from the deep inelastic scattering. The analysis of the whole sets of
experimental data on the electromagnetic form factors of the proton and neutron
with taking into account many forms of PDFs, obtained by the different
Collaborations, make it possible to obtain the special momentum transfer
dependence of the GPDs. This permits us to obtain the electromagnetic and
gravitomagnetic form factors of the nucleons. The impact parameter dependence
of the proton and neutron charge and matter densities is examined. The elastic
hadron scattering at high energies was analyzed in the framework of the model
that takes into account both these form factors (electromagnetic and
gravitomagnetic).
