Elastic Meson-Nucleon and Nucleon-Nucleon Scattering: Models vs. All Available Data
E. Martynov, J. R. Cudell, A. Lengyel
We consider simple-pole descriptions of soft elastic scattering at small and , and allow for the presence of a hard pomeron. We have built and analyzed an exhaustive dataset…
Hard pomeron contribution to forward elastic scattering
J. R. Cudell, A. Lengyel, E. Martynov +1
The introduction of a hard singularity in fits to total cross sections and to the ratio of real to imaginary parts enables to reproduce perfectly the data for sqrt(s)< 100 GeV usin…
A toy model for generalised parton distributions
J. R. Cudell, F. Bissey, J. Cugnon +3
We give the results of a simple model for the diagonal and off-diagonal valence quark distributions of a pion. We show that structure can be implemented in a gauge-invariant manner…
Soft data and the hard pomeron
J. R. Cudell, A. Lengyel, E. Martynov +1
We show that the introduction of an additional, hard, singularity in soft forward amplitudes enables one to improve considerably the fits using a simple-pole structure for the soft…
Saturation and non-linear effects in diffractive processes
O. V. Selyugin, J. R. Cudell
Through a direct implementation of the saturation regime resulting from the unitarity limit in the impact parameter representation, we explore various possibilities for the energy…
A Simple Model for Generalised Parton Distributions of the Pion
J. P. Lansberg, F. Bissey, J. R. Cudell +2
We present here an extension of our model for the pion, which we used previously to calculate its diagonal structure function, to the off-forward case. The imaginary part of the of…
