Odderon
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 ...account, hence an odderon. We use the DL fit as a frameworkfor comparing different odderon contributions to experimental data. To that end we replace their triple-gluon exchange amplitude by one of the model odderon contributions. We retain the original parameter values of the fit and make no attempt to improve it. 2.2. A position-space model1.. Pomeron and Odderon exchanges are the theoretically dominant contributions to hadronic cross sections at high energy. They appear on an equal footing in the QCD description of hadronic reactions, and in the lowest order approximation they correspond to colour singlet exchanges in the t-channel with two and three gluons, respectively.. The relevance of the Odderon exchange for hadronic ...

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.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.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 …An odderon is the hypothetical exchange of an odd number of gluons. Christophe Royon is a Nuclear Physics professor in the KU Department of Physics & Astronomy. "Until now, most models were thinking there was a pair of gluons - always an even number, said Royon. "Now we measure for the first time the higher number of events and properties ...Download PDF Abstract: In the paper we propose and solve analytically the non-linear evolution equation in the leading twist approximation for the Odderon contribution.

As well as the signal, we consider in detail the principle backgrounds, due to QCD-initiated production (i.e., double pomeron exchange) and $\ensuremath{\gamma}\ensuremath{\gamma}$ …Abstract. Inspired by the evidence of the odderon exchange recently observed by the D0 and TOTEM Collaborations, a quantum chromodynamics (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 J P C = 1/2/3±−.The odderon is a 'quasiparticle' — not a real particle, but a phenomena that behaves rather like one. It is a gang of three gluons, the subatomic particles that bind quarks together to form the ...IPPP/18/71 December 3, 2018 Searching for the Odderon in Ultraperipheral Proton{Ion Collisions at the LHC L.A.

From the QCD point of view, the pomeron is made of and even number of gluons (2, 4, 6, etc) which leads to a (+1) parity whereas the odderon is made of and odd number of gluons (3, 5, 7, etc) corresponding to a (1) parity. The scattering amplitudes can be written as:18 Mar 2022 ... NEW TRAILER!? ✨ March 31st can't come soon enough! We're counting the days until the premiere of The Fairly OddParents: Fairly Odder on ...The odderon started out in the early 1970s as a purely a mathematical concept. After the advent of QCD, however, theorists showed that QCD not just allowed but required the existence of such a three-gluon compound. Although the new data favour the existence of the odderon, the TOTEM collaboration prefers to emphasise all the possible …the exchange of colorless objects (pomeron and odderon). Pomeron and odderon correspond to positive and negative charge (C) parity. The odderon is defined as a singularity in the complex plane, located at J = 1 when t = 0 and which contributes to the odd crossing amplitude [3-6]. From the point of view of QCD, the pomeron is made of an evenAdd 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 scattering amplitude describing Odderon exchange enters quadratically in the cross section. This observation lead to the suggestion in Ref. [14], that the study of observ-ables where Odderon effects are present at the amplitude level - and not at the squared amplitude level - is mandatory to get a convenient sensitivity to a rather small ...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).

Odderon asymptotics emerged for the first time in Ref. [1] and is nowadays usually associated with C = -1 exchange in t-channel. Although the studies in QCD [2, 3] (see Refs. [4, 5] for further references) support existence of C=-1 exchange (QCD Odderon), it should be stressed that such exchange need not be mandatory for the Odderon type behavior.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 ...Title: Physics with intact protons at the LHC: from the odderon discovery to the sensitivity to beyond standard model physics Authors: C.

However, when combining this signal with the 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].
