Comparison of $pp$ and $p \bar{p}$ differential elastic cross sections and observation of the exchange of a Colorless $C$-odd gluonic compound

TL;DR

This paper reports the discovery of the odderon, a colorless C-odd gluonic compound, through comparison of elastic differential cross sections in proton-proton and proton-antiproton collisions at high energies.

Contribution

It presents the first experimental evidence for the odderon by analyzing differential cross sections in high-energy elastic scattering.

Findings

Observation of differences in $pp$ and $p ar{p}$ cross sections

Evidence supporting the existence of the odderon

Confirmation of theoretical predictions about C-odd gluonic exchanges

Abstract

We describe the discovery of the colorless $C$-odd gluonic compound, the odderon, by the D0 and TOTEM Collaborations by comparing elastic differential cross sections measured in $pp$ and $p \bar{p}$ interactions at high energies
