Odderon
The perturbative QCD odderon exists in two different states. The first one was proposed as the \(C=-1\) eigenstate of the Hamiltonian for three reggeized gluons (the simplest of the series of the so-called BKP states [1,2,3]).Its properties and conformal invariance were discussed very long ago [4, 5].After several attempts to numerically estimate its intercept ("energy") and wave function ...Request PDF | JIMWLK evolution of the odderon | We study the effects of a parity-odd "odderon" correlation in JIMWLK renormalization group evolution at high energy. Firstly we show that in the ...1. Introduction The description of the Odderon (1) within QCD [2] was in recent years the subject of several studies (3-6J. Being a partner of the Pomeron [7] which carries the quantum numbers of the vacuum and which is well known from the study of diffractive processes, the odderon still remains a mistery.

In December 2020, the D0 and TOTEM Collaborations made public the odderon discovery based on a purely data driven approach in a CERN and Fermilab approved preprint that was later published in Physical Review Letters. In this experimental observation, the TOTEM proton-proton data in the region of the diffractive minimum and maximum was …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 ...Open access article.

(Note that we draw the incoming particles to the right.) The odderon, the C = −1 partner of the pomeron, was introduced in ...In this work, we propose that the odderon is a reggeized odd-glueball tensor spin-3. To demonstrate our proposal, we study the and elastic scattering by including contributions of the spin-3 odderon and spin-2 pomeron exchange in the process. The phenomenological effective Lagrangian approach is used to calculate the and elastic scattering ...Through painstaking work, scientists have found evidence of a quasiparticle that was first imagined as a hypothesis almost 50 years ago: the odderon.. The odderon is a combination of subatomic particles rather than a new fundamental particle - but it does act like the latter in some respects, and the way it fits into the fundamental building blocks of matter makes the discovery a huge moment ...The two last features have been seen in numerical attempts to solve the odderon equation. The initial condition for evolution of the odderon: the three gluon exchange in Born approximation of ...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.Sep 2, 2021 · 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 singularity as does the strong interaction amplitude described in [10]. So, the coincidence of the values of ˆseems accidental, not related with the presence or absence of the Odderon singularity as assumed in [9]. Our conclusion from this reasoning is that no speci c value of the parameter ˆcan be considered asWe apply the formalism developed earlier [1, 2] for studying transverse momentum dependent parton distribution functions (TMDs) at small Bjorken x to construct the small-x asymptotics of the quark Sivers function. First, we explicitly construct the complete fundamental "polarized Wilson line" operator to sub-sub-eikonal order: this object can be used to study a variety of quark TMDs at ...We study the effects of a parity-odd ``odderon'' correlation in Jalilian-Marian--Iancu--McLerran--Weigert--Leonidov--Kovner renormalization group evolution at high energy. Firstly we show that in the eikonal picture where the scattering is described by Wilson lines, one obtains a strict mathematical upper limit for the magnitude of the odderon amplitude compared to the parity-even Pomeron one.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 ...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 ...We summarize the results of including running coupling corrections into the nonlinear evolution equation for diffractive dissociation. We also document a prediction that the NLO QCD odderon intercept is zero resulting from a discussion at the Diffraction 2012 Workshop.Discovery of the odderon.

Az Odderon részecske felfedezésére, mérési adatokból történő biztonságos kimutatására azonban 2021-ig kellett várni. A magyar-svéd kutatócsoport elsőként találta meg először az Odderon létezésének egyértelmű jelét kísérleti adatokban.It is fundamental that the phase of an elastic scattering amplitude is related to its energy variation. We repeat a previous fit to pp and p p ¯ elastic scattering data from 13 to 13000 GeV, taking better account of the very high accuracy of the 13 TeV data. The conclusion remains that there is no evidence for the existence of an odderon in the small-t data.
We consider the reaction γp → π + π − p at high energies. Our description includes dipion production via the resonances ρ, ω, ρ ′ and f 2, 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 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.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 big hope is the discovery of the Odderon in the LHC region by measuring the phase of the amplitudes, i. e. ˆand d˙=dt. It is precisely in this context that the TOTEM datum for ˆat p s = 13 TeV is crucial. We define our Froissaron-Maximal Odderon (FMO) model, valid at t = 0 as a superposition of the Froissaron, Maximal Odderon and ...

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 ...A quasi-real photon interacts as a hadron due to quantum fluctuations into vector mesons or into quark-antiquark pairs. The γγ cross section is composed, Figure 1, by a “soft (VDM)” interaction, which can be described by hadronic phenomenology like the Regge poles, a point like two-photon reaction, γ γ → q q ¯, which is exactly calculable in QED (direct component) and a “hard ...

Based on the AdS/CFT correspondence, we present a holographic de 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].In this paper we extend our recent nonperturbative 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.

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 ...
