    High Energy Elastic pp Scattering in Additive Quark Model

    Get PDF
    High energy pppp and ppˉp\bar p 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

    Diffractive dissociation in high energy pp collisions in Additive Quark Model

    Full text link
    High energy (CERN SPS and LHC) pppp (ppˉp\bar p) 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 arXiv:1406.142

    Real part of pppp scattering amplitude in Additive Quark Model at LHC energies

    Full text link
    Elastic pppp 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

    Heavy Quark Production in Parton Model and in QCD

    Full text link
    The cross sections of heavy quark production in pppp 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 pTp_T distributions of produced heavy quarks are more smooth.Comment: 12 pages, LaTeX, 10 uuencoded-compressed-tar fig

    Baryon Number Transfer in Hadronic Interaction

    Full text link
    The process of baryon number transfer due to string junction propagation in rapidity is considered. It has a significant effect in the net baryon production in pppp collisions at mid-rapidities and an even larger effect in the forward hemisphere in the cases of πp\pi p and γp\gamma p interactions. The results of numerical calculations in the framework of the Quark-Gluon String model are in reasonable agreement with the data.Comment: Latex, 17 figs. in ps files, 1 table.
