Abstract

We predict pp elastic differential cross section at LHC at the c.m. energy s=14 TeV and momentum transfer range |t|=0-10 GeV2, which is planned to be measured by the TOTEM group. The field theory model underlying our phenomenological investigation describes the nucleon as a composite object with an outer cloud of quark-antiquark condensate, an inner core of topological baryonic charge, and a still smaller quark-bag of valence quarks. The model satisfactorily describes the asymptotic behavior of σtot(s) and ρ(s) as well as the measured p̄p elastic dσ/dt at s=546 GeV, 630 GeV, and 1.8 TeV. The large |t| elastic amplitude of the model incorporates the BFKL pomeron in next to leading order approximation, the perturbative dimensional counting behavior, and the confinement of valence quarks in a small region within the nucleon.
