Odderon.

The odderon, being odd under charge conjugation, couples with different signs to protons and antiprotons and can hence account for that difference. We describe the odderon in leading order perturbation theory, as a perturbative three-gluon exchange in a C = -1 state. We assume that the scale 1.3 GeVz is large enough for perturbation theory to ...6 Sept 2021 ... In QCD, the Pomeron and the Odderon correspond to the exchange of two (or even number of) and three (or odd number of) gluons as shown by Figure ...Odderon Exchange from Elastic Scattering Differences between p p and p p ¯ Data at 1.96 TeV and from p p Forward Scattering Measurements V.

Lett. 127, 062003 – Published 4 August 2021Apr 2, 2019 · 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 ...

To make numeral estimates more definite, we limit ourselves by the region Mp+p- = 1.1 ÷ 1.5 GeV, where in the odderon mechanism of dipion production, the production via single f2(1270) resonance ...The numerical results found show that the inclusion of odderon loops enhances the pomeron propagators but somewhat damps the pA amplitudes. 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.

In the case of nuclear targets, the Odderon cross section becomes enhanced thanks to the mass number of the nuclear target. The gluon saturation effect induces a shift in the diffractive pattern with respect to the Primakoff process that could be used as a signal for the Odderon.Note that in the Ref. [24] the authors dealt with oddballs and odderon Regge trajectories, also using the hardwall model, however relating the ground state for the odd glueballs 1 −− to a ...

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.March 8. An Odd New Result of Hungarian and Swedish Researchers: Discovery of a long awaited but totally surprising new particle, the Odderon.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 ...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.

field of research. For example, the study on odderon contribution based on diquark model and QCD-inspired model can be found in [48] and [49] respectively. Our recent approach on odderon as a Regge oddball spin-3 with the DL propagator gives a theoretical basis for the odderon calculation and satisfies several experimental results inppand p¯p

We explore the possibility of observing odderon exchange in proton-ion collisions at the LHC, via the ultraperipheral photoproduction of C-even mesons. As well as the signal, we consider in detail the principle backgrounds, due to QCD-initiated production (i.e., double pomeron exchange) and $\ensuremath{\gamma}\ensuremath{\gamma}$ …

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.22 Aug 2023 ... This is "Asylgade 19 - Odder Nybolig Odder" by Diakrit on Vimeo, the home for high quality videos and the people who love them.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 ...In the first part of the talk, we will describe the odderon discovery by the TOTEM and D0 experiments. The analysis compares the p pbar elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in pp collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV. The two data sets ...The odderon appears naturally in perturbative QCD. As one can see from Fig. 1 the QCD odderon describes the exchange of three gluons and all the interactions between them. The QCD odderon has the trajectory with the intercept equal to 1, which does not depend on t [16,17]. Hence, the odderon only contributes to the real part of the scattering ...

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 ...Another odderon trajectory with 3g glueballs of Y-shape, corresponds to 11% higher masses and low intercept.

Odderon is a fundamental concept of physics, says Basarab Nicolescu, Honorary Member of the Romanian Academy, the physicist who invented and named the Odderon. ParaCrawl Corpus. In collaboration with Evgenij Martynov, we now design a model based on two concepts: Odderon and Froissaron.

The TOTEM collaboration at CERN has uncovered possible evidence for a subatomic three-gluon compound called an odderon, first predicted in 1973. The result derives from precise measurements of the probability of proton-proton collisions at high energies, and has implications for our understanding of data produced by the LHC and future colliders.

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].to the C-even Pomeron, also a C-odd Odderon exchange is needed to describe the data.

This Regge trajectory for the odderon is represented in Fig. 3 (left panel) and is in agreement with [29] within the non ...Odderon (iny own approach, based on asymptotic theorems, included). CGC fully shows that the Pomeron- Odderon phase is an un-escapable feature of the QCD at high energies and this is, of course, really fundamental. In such a fornzulation, one can assert that the Odderon is a crucial test of QCD. Yuri ...The most reasonable appropriate hadron state in the Odderon channel is the ω meson. Therefore the growth of the Odderon radius with energy is expected to be less than the growth of the black disk radius driven by the even-signature amplitude, and the whole Odderon contribution will be ‘absorbed’ (i.e. power of s suppressed) by the black …In the first part of the talk, we will describe the odderon discovery by the TOTEM and D0 experiments.
