Odderon.

The TOTEM experiment (TOTal Elastic and diffractive cross section Measurement) is one of the nine detector experiments at CERN's Large Hadron Collider.The other eight are: ATLAS, ALICE, CMS, LHCb, LHCf, MoEDAL, FASER and [email protected] shares an interaction point with CMS. The detector aims at measurement of total cross section, elastic scattering, and diffraction processes.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.A search for contributions to the reaction ep → eπ • N * from photon-Odderon fusion in the photoproduction regime at HERA is reported, at an average photon-proton centre-ofmass energy W = 215 GeV. The measurement proceeds via detection of the π • decay photons, a leading neutron from the N * decay, and the scattered electron.In the present paper, we extend the Froissaron-Maximal Odderon (FMO) approach at t different from 0. Our extended FMO approach gives an excellent description of the 3266 experimental points considered in a wide range of energies and momentum transferred. We show that the very interesting TOTEM results for proton-proton differential cross-section in the range 2.76-13 TeV, together with the ...

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 …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 toA search for contributions to the reaction ep → eπ • N * from photon-Odderon fusion in the photoproduction regime at HERA is reported, at an average photon-proton centre-ofmass energy W = 215 GeV. The measurement proceeds via detection of the π • decay photons, a leading neutron from the N * decay, and the scattered electron.

For the pomeron-odderon system the relation between the descriptions in the reggeized gluon (BFKL) framework and the color dipole/CGC one is investigated. Discover the world's research 20+ million ...The Odderon, a charge-conjugation-odd partner of the Pomeron, has been a puzzle ever since its introduction in 1973. The Pomeron describes a colorless exchange with vacuum quantum numbers in the t-channel of hadronic scattering at high energies. The concept was originally formulated for the non-perturbative regime of Quantum Chromodynamics (QCD).

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 ...Odderon [20-27] correspond respectively to positive and negative C parity. 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:The wave function of the Odderon and other multi-gluon composite states satisfies the BKP equation. The corresponding Hamiltonian in the multi-color limit has the properties of the Möbius invariance, holomorphic separability, duality and integrability. We discuss various approaches applied to the solution of the BKP equation for the singlet ...Mar 22, 2021 · By Lund University March 22, 2021. For 50 years, the research community has been hunting unsuccessfully for the so-called Odderon particle. Now, a Swedish-Hungarian research group has discovered the mythical particle with the help of extensive analysis of experimental data from the Large Hadron Collider at CERN in Switzerland.

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.

For the 3--quark system, we focus on the ...

The Odderon is the leading exchange in hadronic scattering processes at high energies in which negative charge conjugation and parity quantum numbers are transferred in the t-channel. We review the origin of the Odderon in Regge theory, its status in perturbative and nonperturbative Quantum Chromodynamics, as well as its phenomenology.

Abstract. In this short note, we report a di-quark model calculation for the spin dependent odderon and demonstrate that the asymmetrical color source distribution in the transverse plane of a transversely polarized hadron plays an essential role in yielding the spin dependent odderon. This calculation confirms the earlier finding that the spin ...The present study shows that, beyond any doubt, the new TOTEM datum $\rho^{pp} = 0.098 \pm 0.01$ can be considered as the first experimental discovery of the Odderon, namely in its maximal form.the Odderon to diffractive production of charmed jets. By forming a charge asymmetry in the energy of the charmed jets, we can determine the relative importance of the Pomeron (C= +) and the Odderon (C= −) contributions, and their interference, thus providing a new experimental test of the separate existence of these two objects. Since the ...The photon-Odderon contribution has a large normalisation uncertainty but the enhances cross-section in the forward region combined with a large asymmetry increases the chance of experimentally detecting the Odderon.
