The Odderon particle is what briefly forms when protons collide in high-energy collisions, and in some cases do not shatter, but bounce off one another and scatter. Protons are made up of quarks and gluons, that briefly form Odderon and Pomeron particles.

Pomeron is a Reggeon with the intercept close to 1. “Hard” Pomeron is a substitute for the following sentence: the asymptotic for the cross section at high energy for the “hard” processes which occur at small distances of the order of $1/Q$ where $Q$ is the largest transverse momentum scale in …

Protons are made up of quarks and gluons, that briefly form Odderon and Pomeron particles. High energy pp andpbar p data on elastic scattering and total cross sections are analyzed in a model including the pomeron, odderon and secondary reggeons. A dipole model is used for the pomeron and for the odderon.

Abstract We show that the asymmetry in the fractional energy of charm versus anticharm jets produced in high energy diffractive photoproduction is sensitive to the interference of the Odderon ( C =−) and Pomeron ( C =+) exchange amplitudes in QCD. We predict the dynamical shape of the asymmetry in a simple model and estimate its magnitude to be of the order 15% using an Odderon coupling to

Their couplings with various proton polarization states can be completely parametrized by the generalized transverse momentum dependent distributions (GTMDs) [34]. Indeed, the gluon Sivers function [36] at small-x is connected to the Odderon in the forward limit [29–31] and participates In this paper we extend our recent non perturbative functional renormalization group analysis of Reggeon Field Theory to the interactions of Pomeron and Odderon fields. We establish the existence of a fixed point and its universal properties, which exhibits a novel symmetry structure in the space of Odderon-Pomeron interactions.

Meanwhile, the more commonly seen quasiparticle made up of an even number of gluons is called a pomeron, after the Soviet theoretical physicist Isaak Pomeranchuk. Abstract We show that the asymmetry in the fractional energy of charm versus anticharm jets produced in high energy diffractive photoproduction is sensitive to the interference of the Odderon ( C =−) and Pomeron ( C =+) exchange amplitudes in QCD. We predict the dynamical shape of the asymmetry in a simple model and estimate its magnitude to be of the order 15% using an Odderon coupling to While both Pomeron and Odderon contribute to helicity-flip processes in general, in the forward limit t= 0 only the double helicity-flip amplitude ϕ2, dominated by the spin-dependent Odderon, survives. This may affect the extraction of the ρ parameter as well as the total cross section in the LHC energy domain and beyond. Our coupling constants for the Pomeron-odderon-ϕ vertex are taken from an analysis of the WA102 data for the p p → p p ϕ reaction. We show that the odderon-exchange contribution significantly improves the description of the p p azimuthal correlations and the dP t “glueball-filter variable” dependence of ϕ CEP measured by WA102.

The QCD describes the Pomeron effect as an interaction in which protons exchange an even number of gluons. In contrast, Odderon is an interaction which leads to an exchange of an odd number of gluons. A glimmer of hope. Though QCD predicts the existence of both these effects, scientists have only found experimental evidence for the Pomeron effect.

Noun . odderon (plural odderons) The hypothetical counterpart of the pomeron, carrying odd charge parity. Translations . Pomerons and odderons At low energies, differences in pp vs pp̄ scattering are due to the exchange of different virtual mesons. At multi-TeV energies, on the other hand, proton interactions are expected to be mediated purely by gluons. The Pomeron exchange contributions are related to multi-gluon exchanges in QCD, which are color singlet bound state of Reggeized gluons, such as tensor glueball and Odderon. The Odderon particle is what briefly forms when protons collide in high-energy collisions, and in some cases do not shatter, but bounce off one another and scatter.
