Ultrahigh energy neutrino physics
J. Kwiecinski, A. D. Martin, A. M. Stasto
We discuss a problem concerning the ultrahigh energy neutrino propagation through the Earth. We present calculation of the neutrino-nucleon cross section at high energies, based on…
Off-diagonal parton distributions and their evolution
K. Golec-Biernat, A. D. Martin
We construct off-diagonal parton distributions defined on the interval 0 < X < 1 starting from the off-forward distributions defined by Ji. We emphasize the particular role played…
Diffractive dijet photoproduction as a probe of the off-diagonal gluon distribution
K. Golec-Biernat, J. Kwiecinski, A. D. Martin
We propose exclusive diffractive dijet photoproduction as an ideal measure of the off-diagonal gluon distribution at high scales. We solve the off-diagonal evolution equations for…
Single particle spectra in deep inelastic scattering as a probe of small dynamics
J. Kwiecinski, S. C. Lang, A. D. Martin
We study the transverse momentum () spectrum of charged particles produced in deep inelastic scattering (DIS) at small Bjorken in the central region between the current je…
A unified BFKL/DGLAP description of Deep Inelastic Scattering
J. Kwiecinski, A. D. Martin, A. Stasto
We introduce a coupled pair of evolution equations for the unintegrated gluon distribution and the sea quark distribution which incorporate both the resummed leading BF…
The description of F2 at small x incorporating angular ordering
J. Kwiecinski, A. D. Martin, P. J. Sutton
We study the perturbative QCD description of the HERA measurements of using a gluon distribution that is obtained from an evolution incorporating angular ordering of…
