  1. 63. Photon content of polarized and unpolarized Proton

    Oral
    We investigate the QED Compton process (elastic and inelastic) in unpolarized and longitudinally polarized electron-proton scattering. The cross section can be expressed in terms of the equivalent photon distribution of the proton. We show that this process can be used to extract the photon content of both polarized and unpolarized proton at future colliders over a broad kinematical range.
  2. 25. Lepton distribution as a probe of new physics in production and decay of $t$-quark and its polarization

    Top and QCD
    Oral
    We investigate the possibilities of studying possible new physics in various processes of t-quark production using the kinematical distributions of the secondary lepton coming from decay of t-quarks. We show that the angular distributions of secondary lepton are insensitive the anomalous tbW vertex and hence is a pure probe of new physics in a generic process of t-quark production. The...
  3. 149. Gamma Gamma Total Cross-sections

    Top and QCD
    Oral
    We explore the predictions for the total hadronic gamma gamma cross-sections in a mini-jet model, which includes the effect of soft-gluon resummation. The non-perturbative parameters in the model are determined from the values obtained in a good fit to the pp and proton-antiproton data and the Vector Meson Dominance Model. Recently we studied dependence of the parameters...
  4. 187. Use of highly polarized electrons

    Oral
    The access to the purest initial state is possible by use of two highly polarized electrons. We give an up-to-date review of where we stand in this effort - including its accessibility in the context of its basic compatibility with the beamline and detector used for e+e- - initiated interactions.
