Particle Physicists Confirm Existence of Odderon | Odderon Particles.HISTORY The odderon was born in 1973 and it was then motivated by the surprising data provided by the ISR : the increase of the total cross-sections which seemed to show that the In2s Froissart-Martin bound could be saturated. This led Lukaszuk and Nic~lescuI to the hypothesis that the strong interactions could be as strong as possible, i.e ...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 toInspired 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.

In particular, the odderon propagator strongly falls with energy in agreement with conclusions from the QCD. Remarkably the influence of odderon loops is clearly felt both in the propagators and amplitudes.A search for contributions to the reaction ep→eπ0N∗ from photon-odderon fusion in the photoproduction regime at HERA is reported, at an average photon-proton centre-of-mass energy 〈W ...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 show how to find it at RHIC and LHC. The most spectacular signature of the odderon is the predicted difference between the differential cross-sections for proton-proton and antiproton-proton at high s and moderate t.Download scientific diagram | A background to the odderon searches based on Fig. 1(b) arising from the production of C-even mesons by pomeron-pomeron fusion. from publication: Searching for the ...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 asThe recent TOTEM data [] for the parameter \(\rho \), which describes the ratio between the real and imaginary parts of the scattering amplitude, has motivated an intense debate about the possible contribution of the Odderon [2,3,4,5,6,7,8,9,10].Such object is a natural prediction of the Quantum Chromodynamics (QCD), has a C-odd …The recent TOTEM data [] for the parameter \(\rho \), which describes the ratio between the real and imaginary parts of the scattering amplitude, has motivated an intense debate about the possible contribution of the Odderon [2,3,4,5,6,7,8,9,10].Such object is a natural prediction of the Quantum Chromodynamics (QCD), has a C-odd parity and determines the hadronic cross section difference ...Mar 16, 2021 · The odderon was hypothesized in 1973 under the Regge theory of strong interactions. In “quantum chromodynamics,” the theory of quark and gluon interaction, this is represented by a compound of three gluons. But, until now, the odderon’s existence has remained conjectural and considered by some as a mere academic discussion. odderon states and so its Green function remain unknown and the relevant technical problems seem great. This is a problem for future studies. 2. 2 pp and pp¯ elastic scattering. Phenomenological description We use the normalization in which the differential cross-section for pp and pp¯ scattering is given byThe odderon remains an elusive object, 33 years after its invention.

TAKE SURVEY.We discuss the definition and the energy evolution of scattering amplitudes with C-odd (“odderon”) quantum numbers within the effective theory for the color glass condensate (CGC) endowed with the functional, JIMWLK, evolution equation.We explicitly construct gauge-invariant amplitudes describing multiple odderon exchanges in the …Jan 31, 2018 · Physicists have imagined the existence of the odderon for many decades, but until the LHC began operating at its highest energies in 2015, the odderon remained mere conjecture. The data collected and presented in the new paper was collected at 13 teraelectronvolts (TeV), the fastest scientists have ever been able to collide protons. 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 toInspired 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 is also a color singlet exchange but has negative C-parity and can therefore lead to differences between particle-particle and particle-antiparticle scattering if it is not strongly suppressed at high energies, that is if its intercept is not far below one. In QCD the Odderon can be formed by three gluons in a symmetric color state.12 Apr 2021 ...

The result was presented on Friday 5 March during a meeting at CERN, and ...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.The use of pomeron/odderon trajectories in central exclusive production is outlined in Sec. 3. A simple analytic Regge trajectory is presented in Sec. 4. Single and double pole Regge fits to elastic scattering data are described in Sec. 5 and Sec. 6. Pomeron-pomeron and odderon-odderon total cross sections are derived in Sec. 7. Masses and ...evolved Odderon at a electron-ion collider.

(Note that we draw the incoming particles to the right.) The odderon, the C = −1 partner of the pomeron, was introduced in ...effects coming from inclusion of the Odderon fields and higher order Pomeron couplings. The Odderon is a funda-mental prediction of perturbative QCD, which is a color singlet state of gluons with odd parity. Recently, the D0 and Totem collaborations, studying the difference between pp and pp cross sections at different energies, concluded¯In perturbative QCD the odderon is a $C$-odd color singlet consisting of at least three $t$-channel gluons exchanged with the target. By using the Color Glass …Nov 26, 2021 · We 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 ... 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.The odderon intercept appeared to be smaller than unity, meaning that C-odd amplitudes should decrease with energy. In a following analysis, however, it was discovered by Bartels, Lipatov and Vacca (BLV) [19] that the normalizability condition of the holomorphic wave functions may be relaxed, leading to a new odderon solution, having a flat ...to the C-even Pomeron, also a C-odd Odderon exchange is needed to describe the data. After the proposal of Lukaszuk and Nicolescu [ 5 ] in 1973, it was the ISR data for dσ dt whichThe 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 elasticSep 2, 2021 · Discovery of the odderon.
