High Energy Elastic pp Scattering in Additive Quark Model
High energy and elastic scattering is treated in the framework
of Additive Quark Model. The reasonable agreement with experimental data is
achieved with the natural parameters for the strong matter distribution inside
proton.Comment: 13 pages, 6 figures, 1 table, Revision accepted by JHE
Real part of scattering amplitude in Additive Quark Model at LHC energies
Elastic scattering at LHC energies is treated in Additive Quark Model
together with Pomeron exchange theory. The obtained results are compared with
the new experimental data on the ratio of real to imaginary part of the
scattering amplitude at the small transverse momentaComment: 5 pages, 2 figure
Diffractive dissociation in high energy pp collisions in Additive Quark Model
High energy (CERN SPS and LHC) () scattering is treated in the
framework of Additive Quark Model together with Pomeron exchange theory. The
reasonable agreement with experimental data is achieved both for the elastic
scattering and for the diffractive dissociation with natural parameters for the
strong matter distribution inside proton.Comment: 12 pages, 4 figures, 1 table. arXiv admin note: text overlap with

Heavy Quark Production in Parton Model and in QCD
The cross sections of heavy quark production in collision and for their
photo- and electroproduction are calculated in the framework of QCD. The
virtual nature of the interacting gluons as well as their transverse motion and
different polarizations are taken into account. The obtained cross sections
exhibit more rapid growth with the initial energy than the parton model
predictions and the distributions of produced heavy quarks are more
smooth.Comment: 12 pages, LaTeX, 10 uuencoded-compressed-tar fig
