Odderon.

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.A search for contributions to the reaction ep→eπ 0 N ∗ from photon-odderon fusion in the photoproduction regime at HERA is reported, at an average photon-proton centre-of-mass energy 〈W〉=215 GeV. The measurement proceeds via detection of the π 0 decay photons, a leading neutron from the N ∗ decay, and the scattered electron. No π 0 signal is observed and an upper limit on 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 asOdderon exchEnge from ePEstic scEttering differences between pp End p¯ dEtE Et 1.96TeV End from pp forwErd scEttering meEsurements. Phys. Rev. Lett.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.

Mar 22, 2021 · Physics 22 March 2021 By David Nield TOTEM experiment. (CERN) Through painstaking work, scientists have found evidence of a quasiparticle that was first imagined as a hypothesis almost 50 years ago: the odderon. 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 ...

In this short report, we will study elastic interactions at high energies in order to obtain evidence for the existence of the odderon [].Elastic \(pp\) and \(p\bar{p}\) scattering corresponds to \(pp\rightarrow pp\) and \(p\bar{p}\rightarrow p\bar{p}\) where the protons and antiprotons are intact after interaction, scattered at very small angle and measured in dedicated detectors called roman ...Foto: CERN.

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 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 ...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.

For the dipole odderon, we confirm and extend the non-linear evolution equations recently proposed by Kovchegov, Szymanowski and Wallon, which couple the evolution of the odderon to that of the ...

Their couplings with various proton polarization states can be completely parametrized by the generalized transverse momentum dependent distributions (GTMDs) [34].

In particle physics, the odderon corresponds to an elusive family of odd-gluon states, dominated by a three-gluon state. When protons collide elastically with protons or with anti-protons at high energies, even or odd numbers of gluons are exchanged. Exchanging an even number of gluons is a crossing-even part of elastic proton-proton and proton-antiproton scattering, while odderon exchange ...The combined spin-1 vector odderon (blue square) is r T V 5 and combined spin-3 tensor odderon (red diamond) is r T T 5 .

We introduce a new model of near-forward elastic proton- (anti)proton scattering at high energy based on the modern formulation of Pomeron and Odderon in terms of Wilson lines and generalized TMDs (GTMDs). We compute the helicity-dependent elastic amplitudes ϕ1,2,3,4,5 in ...Within the context of quantum chromodynamics (QCD), P is thought to represent the exchange of a family of colourless crossing-even states, with two-gluon exchange being the simplest contributor [8]. A complementary Regge trajectory, known now as the odderon, with α O ( 0) ≃ 1 but η O = − 1, has been considered as a possible explanation ...

These Odderon signals, the change in B(t) and the disappearance of the diffractive minimum as well as the diffractive maximum, when changing from pp reactions to \(p\bar{p}\) reactions, are rather obvious, stable and clear-cut effects.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 ...The 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 elasticAnother odderon trajectory with 3g glueballs of Y-shape, corresponds to 11% higher masses and low intercept.

the odderon as the tensor particle, not the vector particle. The lowest tensor odderon in its regge trajectory is spin-3 while the slope, intercept and mass of the odderon are poorly understood. In this work, we will investigate the elastic scattering of ppand p p with the contributions of the odderon spin-3.

The Odderon is defined as a singularity in the complex j-plane, located at j = 1 when t = 0 and which contributes to the odd-under-crossing amplitude F −. It was first introduced in 1973 on the theoretical basis of asymptotic theorems [4]. The name "Odderon" itself was introduced two years later [5].

We dis-cuss the theoretical aspects of this approach and consider the phenomenological implications in a variety of processes at high energies, comparing to existing experimental data.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 …THE ODDERON AT RHIC AND LHC arXiv:0707.2923v1 [hep-ph] 19 Jul 2007 Basarab Nicolescu ´ Theory Group, Laboratoire de Physique Nucl´eaire et des Hautes Energies (LPNHE)1 , CNRS and Universit´e Pierre et Marie Curie, Paris To the memory of Leszek Lukaszuk (1938 - 2007) Abstract The Odderon remains an elusive object, 33 years after its invention.Aug 6, 2021 · We describe an analysis comparing the pp[over ¯] 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 using a model-independent approach. The TOTEM cross sections, ex … The Odderon coupling to the proton which we are using is a maximal coupling for the soft Odderon in rela- tion to the soft Pomeron. So on the one hand the ratio may be smaller than this, and on the other hand the ratio may be larger if the hard Odderon and Pomeron have a different ratio for the cou- pling to the proton. For the hard Pomeron the ...The Odderon effects remained elusive for a long time, due to lack of a definitive and statistically significant experimen-tal evidence. 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].The TOTEM collaboration at the LHC, in collaboration 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.
