Odderon.

Pomeron and Odderon in terms of Wilson line correlators. 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 ...The odderon is a 'quasiparticle' — not a real particle, but a phenomena that behaves rather like one. It is a gang of three gluons, the subatomic particles that bind quarks together to form the ...an Odderon exchange. This assumption leads to a reduction in the proton - Odderon - proton coupling, which implies that the Odderon contribution for the elastic scattering is negligible at small - t. In addition, the cross section for the γp → f2(1270)p is strongly suppressed in comparison toIn this short report, we will study elastic interactions at high energies in order to obtain evidence for the existence of the odderon [].Elastic \(pp\) and \(p\bar{p}\) scattering corresponds to \(pp\rightarrow pp\) and \(p\bar{p}\rightarrow p\bar{p}\) where the protons and antiprotons are intact after interaction, scattered at very small angle and measured in dedicated detectors called roman ...PDF | We argue that the so-called maximal Odderon contribution breaks the `black disk' behaviour of the asymptotic amplitude, since the cross section of... | Find, read and cite all the research ...

Inspired by the evidence of the odderon exchange recently observed by the D0 and TOTEM Collaborations, a QCD sum rule investigation is performed to study the odderon as a three-gluon bound state. There may exist six lowest-lying three-gluon odderons with the quantum numbers JPC = 1/2/3±−. We systematically construct their interpolating ...The odderon amplitude without spin-flip falls off with decreasing diquark radius. The contribution of odderon exchange to the ratio Re {ital T}/Im {ital T} for forward {ital pp} scattering is {similar to}0.02 for the symmetric nucleon and {similar to}0.005{endash}0.01 for the nucleon with a compact diquark of radius {similar to}0.2{endash}0.3 F.

Abstract. In this short note, we report a di-quark model calculation for the spin dependent odderon and demonstrate that the asymmetrical color source distribution in the transverse plane of a transversely polarized hadron plays an essential role in yielding the spin dependent odderon. This calculation confirms the earlier finding that the spin ...

differs the odderon contribution from the Pomeron one: (i) the behavior in the vicinity of the saturation scale cannot be derived from the linear evolution in a dramatic difference with the Pomeron case; (ii) a substantial decrease of the odderon contribution with the energy; and (iii) the lack of geometric scaling behavior.We describe the discovery of the colorless -odd gluonic compound, the odderon, by the D0 and TOTEM Collaborations by comparing elastic differential cross sections measured in and interactions at high energies.

The Odderon, a charge-conjugation-odd partner of the Pomeron, has been a puzzle ever since its introduction in 1973. The Pomeron describes a colorless exchange with vacuum quantum numbers in the t-channel of hadronic scattering at high energies. The concept was originally formulated for the non-perturbative regime of Quantum Chromodynamics (QCD).
