Odderon contribution in light of the LHC low-$t$ data

TL;DR

This paper analyzes low-$t$ elastic scattering data from proton-proton and antiproton-proton collisions across a wide energy range to evaluate the potential contribution of the Odderon, using a two-channel eikonal model.

Contribution

It provides a quantitative assessment of the Odderon contribution in elastic scattering data using a two-channel eikonal model that accounts for screening effects.

Findings

Quantitative limits on Odderon contribution at various energies.

Evidence supporting or constraining Odderon effects in low-$t$ scattering.

Enhanced understanding of the interplay between Pomeron and Odderon exchanges.

Abstract

We perform the analysis of elastic scattering $pp$ and $\bar{p}p$ data at low momentum transfer $|t|<0.1$ GeV$^2$ within large collider energy interval $\sqrt{s}=50$ GeV - 13 TeV in order to evaluate quantitatively the possible Odderon contribution. We use the two-channel eikonal model, which naturally accounts for the screening of the Odderon amplitude by $C$-even (Pomeron) exchanges.
