The result was presented on Friday 5 March during a meeting at CERN, and ...as we see from gure1, odderon exchange is not the only C= 1 exchange contribution. Thus, a careful analysis of all contributing C= +1 and C= 1 exchanges is necessary in order to assess the r^ole of the odderon. In this paper we present such a description as is a prerequisite for an experimental search for odderon e ects in the reaction (1.1).

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). Feb 5, 2018 · An odderon—in theory—is a subatomic quasiparticle, meaning something that behaves enough like a particle to be considered one. First theorized back in 1973, it has eluded observation by ... Specially if you add multiple Pomerons and the Odderon. No other phenomenological model is able to match its accuracy. Do we have to go back to the 60's to explain hadron interactions? These plots can be see in slides number 35 and 36 of the following presentation (from a physicist working at the "KEK Theory Center"):

The Real Extended Bialas-Bzdak (ReBB) model is shown here to describe, in the $0.37 \\le -t \\le 1.2$ GeV$^2$ region, the proton-proton elastic differential cross section data published by the TOTEM Collaboration at LHC at $\\sqrt{s} = 8 $ TeV center of mass energy. In this kinematic range, corresponding to the diffractive minimum-maximum region, a model-dependent Odderon signal higher than 18 ...The results were sufficient to claim evidence for the odderon, although not yet its definitive observation. In addition to the new TOTEM-DØ model-independent study, several theoretical papers based on data from the Intersecting Storage Rings, the Super Proton Synchrotron, the Tevatron and the LHC, and on model-dependent inputs, provide ...

The odderon intercept is calculated directly, from its expression via an average energy of the odderon Hamiltonian, using both trial wave functions in the variational approach and the wave function recently constructed by Janik and Wosiek. The results confirm their reported value for the energy. Variational calculations give energies some 30% ...The odderon, on the other hand, has much more subtle signatures.

[39-47] and the review [48] for more discussions. Due to these studies, interests in glueballs are reviving recently. Since the above odderon evidence is still in-direct, it is crucial and important to directly study the ...Discovery of the odderon.

The Odderon is the C-odd partner of the Pomeron, and in QCD it can be represented as a 3-gluon color singlet state. The small x evolution for the Odderon was derived long time ago [1], [2], [3]. Two solutions for the intercept of the Odderon are known.The Odderon could also be found by ATLAS experiment at LHC by performing a high-precision measurement of the real part of the hadron elastic scattering amplitude at small t. 1 Unit´e de Recherche des Universit´es Paris 6 et Paris 7, Associ´ee au CNRS 1 Introduction The Odderon is defined as a singularity in the complex J-plane, located at J ...When protons meet head-on at the Large Hadron Collider (LHC), the collisions provide a micro-laboratory to investigate many phenomena, including the protons themselves. This is the physics that the TOTEM experiment is designed to explore, by taking precise measurements of protons as they emerge from collisions at small angles. This region is …Scientists have uncovered some preliminary evidence for a nuclear physics effect first predicted back in the 1970s. The physics universe you're about to enter into in order to understand it is especially mind-bending. Physicists atAbstract The TOTEM collaboration at the CERN LHC has measured the differential cross-section of elastic proton-proton scattering at p s = 8TeV in the squared four-momentum transfer range 0:2GeV2 < jtj< 1:9GeV2.This interval includes the structure with a diffractive minimum ("dip") and a sec-

Az Odderon egyébként nem az egyetlen olyan részecske, amely elméleti síkon létezik a standard modellben, de nem sikerült még bizonyítani - több olyat keresnek még, amelyben szintén csak gluonok vannak, és kvarkok nincsenek, és amelyek az elmélet több furcsaságára is rámutatnak. az Odderon felfedezése sok ilyen részecske ...We study the odderon contribution to elastic pp and \ (p\bar {p}\) scattering at high energies.

We use a Regge fit by Donnachie and Landshoff as a framework and replace its odderon ...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.dual description the Odderon is the Reggeized Kalb-Ramond field (Bµν) 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. [1]. The con-From Sci-News.com, March 19, 2021: Physicists from the TOTEM (TOTal cross section, Elastic scattering and diffraction dissociation Measurement) Collaboration at CERN's Large Hadron Collider (LHC) and the DØ Collaboration at Fermilab have found strong new evidence for the odderon, an elusive three-gluon state predicted almost five decades ago.Add to this the fact that the Odderon interacts oppositely with antiparticles than with particles, the way to discover of the Odderon is open. Any significant difference between elastic particle-particle scattering and elastic particle-antiparticle scattering in the diffractive dip region at the same collision energy is evidence for the Odderon.

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 Electron of the Future . We can compare our current understanding of the odderon to when the electron was first discovered at the end of the 19th century, said Luine.

The odderon exchange contribution is calculated in nonperturbative QCD, using functional integral techniques and the model of the stochastic vacuum. For the proton we assume a quark-diquark structure as suggested by the small odderon amplitude in pp and pp forward scattering. We show that odderon exchange leads to a much larger inelastic than ...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.

A direct way to probe the Odderon in elastic scattering is by comparing the differential cross-section of particle– particle and particle–antiparticle scattering at sufficiently high energies [3,4].What is the Odderon? The Odderon consists of three gluons. Gluons "glue" the quarks together to "hadrons", particles that are held together by the strong interaction, like the proton and the neutron.
