Gravitation form-factors and spin asymmetries in hadron elastic scattering
Abstract
In the framework of the model, where the scattering amplitude is determined by the first and second moments of the GPDs, the qualitative description of all existing experimental data at s ≥ 52.8 GeV, including the Coulomb range and large momentum transfers, is obtained with only 4 free parameters. The spin-flip amplitude of the nucleon-nucleon elastic scattering is determined taking into account the spin-dependence part of the second moment of the generalized parton distributions (GPDs) with a new set of t -dependence. The corresponding value of the % analyzing power AN for the pp at high energy (RHIC) elastic scattering is obtained.
