The QCD odderon in elastic (anti)proton scattering

TL;DR

This paper calculates the QCD odderon contribution to elastic proton-proton and proton-antiproton scattering, finding it to be very small and undetectable at current collider energies.

Contribution

It provides a detailed calculation of the C-odd amplitude using the Fukugita-Kwiecinski impact factor, highlighting its negligible size in experimental data.

Findings

QCD odderon amplitude is very small

Cannot be observed in current differential cross-section measurements

Supports the idea that odderon effects are suppressed at collider energies

Abstract

The C-odd amplitude for the elastic $pp$ and $p\bar{p}$ scattering due to the exchange of the QCD odderon proposed by J.Bartels, L.N.Lipatov and G.P. Vacca is calculated with the Fukugita-Kwiecinski proton impact factor. The found amplitude is very small and cannot be felt in the differential cross-sections at 2.76 and 1.96 Tev respectively.
