The odderon takes its name from the fact that it appears as an odd-number of gluons moving together, an outcome which would seem to be considerably rarer. 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.

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.

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.

The concept was originally The odderon, the counterpart of the pomeron that carries odd charge parity was introduced in 1973 by Leszek Łukaszuk and Basarab Mar 23, 2021 The odderon is a combination of subatomic particles rather than a new If that number is even, it's the work of a pomeron quasiparticle; the May 13, 2020 We include absorptive corrections at the amplitude level. In order to fix the coupling constants for the photon-Pomeron fusion contribution we Mar 18, 2021 Protons are made up of quarks and gluons, that briefly form Odderon and Pomeron particles.

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.

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. As in our previous analysis, this part of our program aims at the Odderon∗ Lech Szymanowski† LPT, Universite´ Paris XI, CNRS, Orsay, France, Universite de Lie`ge, Belgium and SINS Warsaw, Poland Abstract We study the exclusive production of J/ψor Υ in ppand pp¯ colli-sions, where the meson emerges from the pomeron–odderon and the pomeron–photon fusion. We estimate the cross sections for these pro- The TOTEM and DØ teams compared LHC proton–proton data (recorded at collision energies of 2.76, 7, 8 and 13 TeV and extrapolated to 1.96 TeV), with Tevatron proton–antiproton data measured at 1.96 TeV, and found evidence again for the odderon.When the teams combined the result with measurements at much smaller scattering angles at 13 TeV by the TOTEM collaboration, the significance of the The U.S. Department of Energy's Office of Scientific and Technical Information to the pomeron and to the odderon, taking into account the anomalous dimensions from some QCD beta functions with dynamical corrections, i.e., considering that the dilatonic ﬁeld became dynamical satisfying the Einstein equations in ﬁve dimensions.

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. A dipole model is used for the pomeron and for the 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.

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.

2016-09-10 · We used a dynamical holographic softwall model to obtain even and odd spin glueball mass spectra and achieved the related Regge trajectories associated with the pomeron and the odderon, respectively. These trajectories are in good agreement with those found in [13] , [17] , [22] , [23] , [27] , [28] , [29] .

A simple model for elastic diffractive hadron scattering, reproducing the dip-bump structure is used to analyze pp and ¯pp scattering. The main emphasis is on the delicate and non-trivial dynamics in the dip-bump region, near t=−1 GeV2. The simplicity of the model and the expected smallness of the absorption corrections enables one the control of various contributions to the scattering The odderon takes its name from the fact that it appears as an odd-number of gluons moving together, an outcome which would seem to be considerably rarer. 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.

2010-07-19 · The possible contribution of Odderon (Reggeon with alpha(Odd)(0) ~ 1 and negative signature) exchange to the differences in the inclusive spectra of particle and antiparticle in the central region could be significant at LHC energies. The first data of ALICE Collaboration are consistent with a very small Odderon contribution.
