I hope you like this mani because it really grew on me. ..."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).Odderon-induced π 0 production is expected very close to the beam pipe in the backward direction due to the small values of t and the large photon energy. Two electromagnetic calorimeters covering different regions in polar angle in the backward region are therefore used to detect photons from the π 0 decay, reconstructed as two separate ...The (pomeron and odderon) trajectories may be used to calculate processes of central exclusive diffraction (CED). Discover the world's research. 25+ million members; 160+ million publication pages;expected Odderon state in QCD by studying spin-dependent elastic scattering in a wide t-range with polarized p+ p. 1 Introduction Diffractive processes at high energies are believed to be occurring via the exchange of a color singlet object (the “Pomeron”) with the same quantum numbers as the vacuum (JPC = 0++) [2]. The Pomeron is ...Volume 232, number 3 PHYSICS LETTERS B 7 December 1989 UNITARITY RESTRICTIONS ON THE SUPERCRITICAL ODDERON E.S. MARTYNOV Institute for Theoretical Physics, 252130 Kiev-130, USSR Received 1 July 1989; revised manuscript received 19 September 1989 In a model based upon a supercritical pomeron and odderon, in which unitarity is imposed in the eikonal formalism, we obtain restrictions on the ...In the case of the odderon the wave function in impact-parameter space depends on only one anharmonic ratio and the corresponding functional is signifi- cantly simplified. We discuss in the variational approach the relation between the odderon and the pomeron in QCD. A semi- quantitative argument is given that the intercept of the odderon in ...Odderon exchange dominates except at very small transverse momentum, and we find a cross section of about 20 nb at a centre-of-mass energy of 20 GeV. This result is compared with what is currently ...10 Apr 2023 ... Notwithstanding that, perturbative QCD analyses suggest that the odderon concept is well founded, being linked to the exchange of a family of ...The odderon can be seen as the total contribution coming from all types of odd gluon exchange. It represents the involvement of all of three, five, seven or other odd number numbers of gluons. By contrast, the older model assumes a contribution from all even numbers of gluons, so it includes contributions from two, four, six or more even …The odderon was suggested 50 years ago [1,2] as the C-odd (C ¼ −1) partner of the C-even (C ¼þ1) pomeron in mediating a t-channel colorless exchange in elasticOdderon effects in the differential cross-sections at T evatron and LHC energies 3 4 F roissaron and Maximal Odderon at t 6 = 0 4.1 Partial amplitudes for F roissaron and OdderonThe odderon remains an elusive object, 33 years after its invention. The odderon is now a fundamental object in QCD and it has to be found experimentally if QCD is right. In the present paper, we ...Here \(\Phi \) is the complex pomeron field, \(\Psi \) is the complex odderon field, \(\Phi ^{+}\) and \(\Psi ^{+}\) are their conjugates, \(\mu _P\) and \(\mu _O\) are the pomeron and odderon mass parameters equal to the intercepts minus 1, respectively, the effective coupling constant \(\lambda \) is the same as in the pure pomeron theory ().To take the odderon signature into account its ...A bstractWe consider the reaction γp → π+π−p at high energies. Our description includes dipion production via the resonances ρ, ω, ρ′ and f2, and via non-resonant mechanisms. The calculation is based on a model of high energy scattering with the exchanges of photon, pomeron, odderon and reggeons. The pomeron and the C = +1 reggeons are described as effective tensor exchanges, the ...The authors report an odderon Regge trajectory emerging from a field theoretical Coulomb gauge QCD model for the odd signature J{sup PC} (P = C = -1) glueball states (oddballs). The trajectory intercept is clearly smaller than the pomeron and even the {omega} trajectory's intercept which provides an explanation for the nonobservation of the ...Here we show that in the dual description the Odderon is the Reggeized Kalb-Ramond field (B µν ) in the Neveu-Schwartz sector of closed string theory. To first order in strong coupling, the high energy contribution of Odderon is evaluated for N = 4 Super Yang-Mills by a generalization of the gravity dual analysis for Pomeron in Ref.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).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).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 intercept, α O −1, is given by the maximal eigenvalue of the Hamiltonian and the corresponding eigenfunction determines the odderon wave function χ O (ρ 1, ρ 2, ρ 3). The effective QCD Hamiltonian, H 3 , possesses a number of remarkable properties which allow to solve the odderon problem exactly 3, 10.v. t. e. In particle physics, a glueball (also gluonium, gluon-ball) is a hypothetical composite particle. [1] It consists solely of gluon particles, without valence quarks. Such a state is possible because gluons carry …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 toScaling behaviour of the differential cross section dσ/dt of elastic pp collisions in the ISR energy range of √ s = 23.5−62.5 GeV. The measured differential cross section data are taken from ...We describe the odderon as an effective vector exchange. We emphasise that with a tensor pomeron and a vector odderon the corresponding charge-conjugation relations are automatically fulfilled. We compare the model to some experimental data, in particular to data for the total cross sections, in order to determine the model parameters. …The detection of the Odderon won't change the face of physics, as SUNY Stony Brook astrophysicist Paul Sutter wrote in an article for Live Science in 2019, back when researchers first spotted possible evidence for the particle. Sutter and many other researchers argue that it's not a true particle at all but a quasiparticle, because it's nothing ...Csörgő brought up that the potential existence of Odderon was suggested in 1973, but the particle accelerators available at the time had not yet developed to the point where they could allow for its discovery. 48 years later, Hungarian researchers created a new method of re-analyzing and screening previously reported experiments and data, …We propose to study an odderon exchange in the "pure" processes γγ→MM′, γγ→M jet, ep→eMp (M=π 0, η, η′, η c, etc. Corresponding cross sections with the "bare" odderon as the reggezied three-gluon exchange are estimated.At HERA energies in the process ep→e0 − p one should observe a steep growth (by an order of magnitude) of the "odderon" cross section.The TOTEM collaboration at the LHC, together with the DØ collaboration at the Tevatron collider at Fermilab, have announced the discovery of the odderon – an elusive state of three fundamental particles called gluons that was predicted almost 50 years ago. The result was presented on Friday 5 March during a meeting at CERN, and follows the joint submission in December 2020 of a CERN ...Secondly, the Odderon has recently been shown to naturally emerge from the Color Glass Condensate (CGC), a theory for the high-energy asymptotics of QCD. It has been argued that saturation/CGC effects tend to decrease the Odderon intercept, possibly providing an explanation for the lack of experimental evidence for the Odderon so far.The odderon observation recently published by the D0 and TOTEM collaborations has been widely accepted by a majority of the particle physics community and ...Open access article. Odderon Exchange from Elastic Scattering Differences between pp and p p ¯ Data at 1.96 TeV and from pp Forward Scattering MeasurementsAn even-numbered group of gluons is called a ‘pomeron’, while the odd group is dubbed as an odderon. Despite the rarity with which the odderons are produced, scientists continued to hunt for ...The scattering amplitude with spin-non-fiip and spin-flip components represented by Froissaron, Maximal Odderon as well as by standard Regge poles contributions is considered. From the fit to the data of pp and $$\\bar{p}p$$ p ¯ p scattering at high energy and not too large momentum transfers we found that this model taking …The odderon remains an elusive object, 33 years after its invention.

Evolution equationIt is now straightforward to write down an evolution equation for the odderon in the dipole model. We have shown above that in the dipole model a single step of the small-x evolution for the odderon is the same as for the BFKL pomeron [19].Subsequent steps of the dipole evolution would generate more color dipoles in the onium wave function.Dec 27, 2019 · Moreover, if we leave Odderon Regge pole intercept αO(0) completely free we find a very good solution for αO(0) near −1 in agreement with the result of oddballs spectroscopy in QCD based on ... The Odderon coupling to the proton which we are using is a maximal coupling for the soft Odderon in rela- tion to the soft Pomeron. So on the one hand the ratio may be smaller than this, and on the other hand the ratio may be larger if the hard Odderon and Pomeron have a different ratio for the cou- pling to the proton. For the hard Pomeron the ...Recent results are summarized from the TOTEM experiment at CERN LHC, including measurements of the total, elastic and inelastic cross-sections, the nuclear slope parameter B, the differential cross-section of elastic scattering and the real to imaginary part ration ρ at s√ = 2.76 and 13 TeV.

Figures - available via license: Creative Commons Attribution 4.0 ... For the [27,27] Pomeron we find ω [27,27] = 2ω+O(1/N)>2ω. We also find three charge conjugation odd exchanges, one of which is the unit intercept Bartels-Lipatov-Vacca Odderon, while another one has an interecept greater than unity. We explain in what sense our calculation goes beyond the standard BFKL/BKP calculation.Another interesting hypothetical Regge singularity is the "odderon", which has negative signature and C parity and can be built out of at least 3 gluons. Most studies of the pomeron and odderon singularities in QCD are based on applications of the perturbation theory [14].The two data sets disagree at the 3.4σ level and thus provide evidence for the t-channel exchange of a colorless, C-odd gluonic compound, also known as the odderon.Odderon-ul este un concept fundamental de fizică, precizează fizicianul care a formulat și a dat numele Odderon-ului, Basarab Nicolescu, membru de onoare al Academiei Române. Aflat la Paris, unde trăiește de ani …In recent years, the discovery of the odderon, a colorless C -odd gluonic compound, has been confirmed in the TOTEM and D0 collaborations. However, the spin quantum number of the odderon remains unidentified. In this work, we aim to attribute a spin of J=3 to the odderon in pp elastic scattering by calculating the helicity amplitudes and the ...2.2..

We have shown above that in the dipole model a single step of the small-x evolution for the odderon is the same as for the BFKL pomeron [19].Subsequent steps of the dipole evolution would generate more color dipoles in the onium wave function.It's an odderon, a particle that's even more odd than its name suggests, and it may have recently been detected at the Large Hadron Collider, the most powerful atom smasher, where particles are ...Discovery of the odderon. In the 1950s, experimental data on the total cross-section for proton–proton collisions ( σpp) suggested that σpp was initially decreasing as the collision energy ...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.These Odderon signals, the change in B(t) and the disappearance of the diffractive minimum as well as the diffractive maximum, when changing from pp reactions to \(p\bar{p}\) reactions, are rather obvious, stable and clear-cut effects.Odderon exchange dominates except at very small transverse momentum, and we find a cross section of about 20 nb at a centre-of-mass energy of 20 GeV. This result is compared with what is currently ...arXivLabs: experimental projects with community collaborators. arXivLabs is a framework that allows collaborators to develop and share new arXiv features directly on our website.For the dipole odderon, we confirm and extend the non--linear evolution equations recently proposed by Kovchegov, Szymanowski and Wallon, which couple the evolution of the odderon to that of the pomeron, and predict the rapid suppression of the odderon exchanges in the saturation regime at high energy. For the 3--quark system, we focus on the ... The odderon amplitude without spin-flip falls off with decreasRecent results are summarized from the TOTEM experi By using the model parameters, the Chew-Frautschi plot of the tensor odderon Regge trajectory is evaluated. As a result, the odderon spin-3 mass is predicted to be 3.2 GeV. In addition, the total cross-section of our model is compatible with the results from TOTEM and its extrapolation from D0 collaboration.Title: Odderon Searches 1 Vth Workshop on Small-x and Diffractive Physics Odderon Searches and Hadronic Final States in Diffractive Scattering at HERA Karlheinz Meier Kirchhoff-Institut für Physik Ruprecht-Karls-Universität Heidelberg 2 Language of Diffraction in a factorized view Q2 (momentum transfer describing photon virtuality A bstractWe consider the reaction γp → π+π−p at high Below we will try to trace almost a half-of-century history of the Odderon concept and attempts and e orts to nd its experimental manifestations. 1Speaker 2Later the Odderon option as formulated in [1] was dubbed (after serious mod cations) the "Maximal Odderon" in contrast to other Odderon incarnations (e.g. as a C-odd Reggeon).
