چکیده
In the leading twist approximation of the Wilson operator product expansion with standard and “frozen” versions of strong copling constant we show that the Besselinspired behavior of the structure function F2 at small x, obtained for a flat initial condition in the DGLAP evolution, leads to very good agreement with the deep inelastic scattering experimental data from HERA.

We investigate the Q 2 evolution of parton distributions at small x values, obtained in the case of flat initial conditions. The results are in excellent agreement with deep inelastic scattering experimental data from HERA.

This talk presents results from the QCDSF-UKQCD collaboration for moments of leading twist generalized parton distributions in two-flavor lattice QCD based on O(a) improved Wilson Fermions. We study helicity independent and helicity flip GPDs with a focus on densities of quarks in the transverse plane.

We show that in the lattice Hamiltonian limit the static transverse propagator D(| p|) ∝ d p 0 D(| p|, p 0) satisfies multiplicative renormalizability. We give a procedure to calculate D(| p|) on available lattices at finite temporal spacing. The result agrees at all momenta with the Gribov

Rapidity divergences occur when parton densities in a gauge theory are defined in the most natural way, as expectation values of partonic number operators in light-front quantization. I review these and other related divergences, and show how the definitions of parton densities can be modified to remove the divergences. A modified definition is not only essential for many phenomenological appli...

Several supersymmetric models with extended gauge structures predict light doubly-charged Higgsinos. Their distinctive signature at the large hadron collider is highlighted by studying their production and decay characteristics.
