In this work, we perform a comparison of the use of distinct gluon propagators with the experimental data in diffractive processes, pp elastic scattering and light meson photo-production. The gluon propagators are calculated through nonperturbative methods, being justified their use in this class of events, due to the smallness of the momentum transfer. Our results are not able to select the best choice for the modified gluon propagator among the analyzed ones. This shows that the application of this procedure in this class of high energy processes, although giving a reasonable fit to the experimental data, should be taken with same caution.

Taking into account the PDFs, obtained by different Collaborations, the momentum transfer dependenceof GPDs of the nucleons is obtained. The calculated electromagnetic and gravitomagnetic form factors ofnucleons are used for the description of different form factors and the nucleons elastic scattering in a wide energy and momentum transfer region with a minimum number of fitting parameters. The electromagnetic and gravitomagnetic radii of the nucleon are calculated using the obtained momentum transfer dependence of GPDs with different forms of PDFs obtained by different Collaborations. The comparison of the calculations, taking into account the PDFs obtained by different Collaborations, of ean square electromagnetic and gravitomagnetic radii of nucleons is made.

We show that the axial-vector coupling of Z0(W±) to quarks, when acting together with the emission of a hypothetical spin-zero jet-generating quantum coupled to quarks results in an unusual behavior in certain processes, at high energy and momentum transfer. This involves an excess jet production at the subpicobarn level.
