Hard and soft pomerons in elastic nucleon scattering

Abstract

An analysis of the possible contribution of the hard pomeron in elastic hadron scattering at LHC energies is made. It is shown that such a contribution has affected the shape of the differential cross section in the Coulomb-hadron interference region and in the dip region. On the basis of the new High-Energy General Structure (HEGS) model, the possible contributions of the hard pomeron are investigated. The predictions of the model at $8$ TeV are discussed.
