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.

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.

Pomeron and odderon exchange can thus explain the energy independence of the asymmetry and predicts that the asymmetry should persist in events with large rapidity gaps. Originalspråk engelska

Pomerons and odderons. At low energies, differences in pp vs pp̄ scattering are due to the exchange of different virtual mesons.

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.

Indeed, the gluon Sivers function [36] at small-x is connected to the Odderon in the forward limit [29–31] and participates Pomeron and Odderon: / and electroproduction Tomasz Stebel Institute of Nuclear Physics PAN with Adrian Dumitru (Baruch College, NY, USA) Based on: A. Dumitru and TS, Phys. Rev. D 99, 094038 (2019) Using a model with mildly energy dependent form factors as input and performing full eikonalization before we compare with the data, the answer that we find from a careful examination of the various options is that the odderon is indeed necessary if: 1) we trust the ISR pp data to be precise enough that their comparison with the collider data on pc {Mathematical expression} is meaningful, 2 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. 2021-02-23 · In Ref. , a phenomenological Reggeon + Pomeron + Odderon exchange model is employed to study, in particular, the possible hollowness effect in the high-energy elastic pp collisions. A similar study of the Philips-Barger model was performed in Ref. using the most recent TOTEM data on elastic pp scattering.

March 2021; DOI: 10.13140/RG.2.2.24551.57764 The pomeron is generally believed to be responsible for a wide variety of phenomena, such as elastic scattering, rapidity gaps, and vector meson production. In addition, a CP-odd partner of the pomeron, the odderon, has been postulated from theoretical considerations, but could not yet be established experimentally.

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. 2021-03-23 · 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.

2021-03-19 · When it’s an even-numbered group of gluons (two, four, etc.), we call it a pomeron. When the number of gluons in the group is odd (three, five, etc.), well, you guessed it: That’s an odderon.

The possible contribution of Odderon If that number is even, it's the work of a pomeron quasiparticle ; the other option – which seems to happen much less often – is an odderon quasiparticle, a compound with an odd number of gluons. Until now, scientists have been unable to spot odderons in experiments, even though theoretical quantum physics has suggested they should exist. odderon (plural odderons) (physics) The hypothetical counterpart of the pomeron, carrying odd charge parity. 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. 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.

However di erence of particle anti-particle cross sections are given by a so-called Odderon carrying C = -1 quantum numbers identi ed in weak coupling with odd numbers of exchanged gluons. Here we show that the dual description associates this with the Neveu-Schwartz (B
