Odderon — Odderon, motsvarigheten till pomeron som bär udda laddningsparitet infördes 1973 av Leszek Łukaszuk och Basarab Nicolescu .
When the number of gluons in the group is odd (three, five, etc.), well, you guessed it: That’s an odderon. We consider the first LHC data for pp collisions in the framework of Regge theory. The integral cross sections and inclusive densities of secondaries are determined by the Pomeron exchange, and we present the corresponding predictions for them. The first measurements of inclusive densities in midrapidity region are in agreement with these predictions. The possible contribution of Odderon The Pomeron and Odderon ideas have stuck around, and scientists have previously found experimental evidence for the Pomeron, but not the Odderon. QCD describes the Pomeron as protons exchanging an The odderon takes its name from the fact that it appears as an odd-number of gluons moving together. Meanwhile, the more commonly seen quasiparticle made up of an even number of gluons is called a 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.
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.
Ang pomeron ay maiging natanggap noong mga 1960 sa kabila ng katotohanang ang mga nasukat na seksiyong krus ng proton-proton at proton-antiproton na pagkakalat sa mga enerhiyang makukuha nang mga panahong ito ay hindi magkatumbas. Odderon. Ang odderon ang hipotetikal na kapilas (counterpart) ng
March 2021; DOI: 10.13140/RG.2.2.24551.57764 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. Odderon-Pomeron interference.

And now a research team, involving researchers from Lund University, has succeeded in identifying the Odderon in connection with an advanced data analysis study at the particle accelerator CERN.
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
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. We consider the first LHC data for pp collisions in the framework of Regge theory.

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 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.

Odderon is a cousin of Pomeron which emerged already about half century ago in the so called Regge theory to explain the logarithmically rising (rather than decreasing) cross sections in proton-proton and proton-antiproton collisions. Pomeron is part of low energy phenomenology and perturbative QCD cannot say much about it. 2019-04-10 · For this purpose, we employ an effective Lagrangian approach by using the tree-level Born approximation, and various experimental and theoretical inputs. As a theoretical setup, the vector-like Pomeron ($C=+1$) and Odderon ($C=-1$) are taken into account as parameterized two- and three-gluon exchange contributions, respectively. Pomeron is a Reggeon with the intercept close to 1. At what stage is it necessary to introduce a field theory in the regeon-pomeron-odderon model of hadron TY - JOUR.
