The perturbative odderon in elastic pp and pp̄ scattering

The evidence for the existance of an odderon [1] remains scarce. To date, the best evidence comes from the differential cross section in elastic pp and pp̄ scattering. The pp data show a dip structure at −t ≈ 1.3 GeV while the pp̄ data only flatten off at that point. The odderon, being odd under charge conjugation, couples with different signs to protons and antiprotons and can hence account for ...

The Odderon in High Energy Elastic pp Scattering ∗ Hans

We study the Odderon contribution to elastic pp and pp̄ scattering at high energies. Different models for the Odderon–proton coupling are considered and their effects on the differential cross section in the dip region are investigated. We use a Regge fit by Donnachie and Landshoff as a framework and replace its Odderon contribution by the different models. We consider two models for the Odderon...

Transverse Imaging of the Proton in Exclusive Diffractive Pp Scattering

In a recent paper we describe a new approach to rapidity gap survival (RGS) in the production of high–mass systems (H = dijet, Higgs, etc.) in exclusive double–gap diffractive pp scattering, pp → p+H+p. It is based on the idea that hard and soft interactions are approximately independent (QCD factorization), and allows us to calculate the RGS probability in a model–independent way in terms of t...

A Multiparton Model for pp / pp Inelastic Scattering

We have applied a geometrical approach to study pp / pp inelastic scattering over the range of center mass energies from 44.5 to 900 GeV. The multiplicity distributions are described by multiple parton-parton collisions without free parameters. The output seems to be consistent with data and the results are discussed. Exploring the possible connection between impact parameter representation of ...
