In particle physics, the odderon corresponds to an elusive family of odd-gluon states, dominated by a three-gluon state. When protons collide elastically ...Jan 31, 2018 · Physicists have imagined the existence of the odderon for many decades, but until the LHC began operating at its highest energies in 2015, the odderon remained mere conjecture. The data collected and presented in the new paper was collected at 13 teraelectronvolts (TeV), the fastest scientists have ever been able to collide protons.

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).We study the rapidity dependence of the central exclusive production cross sections of C-even mesons in pA and AA collisions, where A is a heavy ion. We observe qualitatively different behaviour of the contributions arising from \(\gamma \)-Odderon and Pomeron–Pomeron fusion mechanisms.This can be used to extract the Odderon signal …In this work, we consider a massive gauge boson field in ${\\mathrm{AdS}}_{5}$ dual to odd glueball states with twist-5 operator in 4D Minkowski spacetime. Introducing an IR cutoff, we break the conformal symmetry of the boundary theory allowing us to calculate the glueball masses with odd spins using Dirichlet and …Download a PDF of the paper titled Odderon: Lost or/and Found?, by Vladimir Petrov and 1 other authors Download PDF Abstract: This is a quick survey of theoretical and experimental efforts to understand and identify the Odderon.

Theory and phenomenology of the η c photo- and electroproduction is developed from the point of view of probing the odderon singularity in QCD which corresponds to the three gluon exchange mechanism. This mechanism leads to cross-sections which are independent of W 2 for the exchange of three non-interacting gluons or exhibit an increase with increasing W 2 (or 1 x) for the odderon intercept ...We explore the possibility of observing odderon exchange in the pp→ppK+K− and pp→ppμ+μ− reactions at the LHC. We consider the central exclusive production (CEP) of the ϕ(1020) resonance ...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 and which does not depend on t[16, 17]. Hence, the Odderon only contributes to the real part of the scattering amplitude. For an estimate we will use the following formAlthough the Odderon is an unambiguous prediction of Quantum Chromodynamics, its existence still was not confirmed experimentally. One of the processes where the Odderon contribution is expected to be dominant is the diffractive photoproduction of tensor mesons. In this paper we study the diffractive f2(1270) photoproduction in pA collisions at LHC and RHIC considering the model of the ...Enter the email address you signed up with and we'll email you a reset link.

Mar 16, 2021 · 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. The result was presented on Friday 5 March during a meeting at CERN, and ... The existence of odd charge-conjugation, zero flavor-number exchange contributions to high energy hadron scattering amplitudes is a basic prediction of quantum chromodynamics, following simply from the existence of the color-singlet exchange of three reggeized gluons in the t-channel [1].In Regge theory, the "Odderon" contribution is dual to a sum over C=P=−1 gluonium states in the t ... ….

In the saturation regime, the expectation value of odderon that incorporates multiple gluon exchange effect has been computed in the MV model [1] with a cubic term [27]. The energy dependence of the odderon exchange is described by the BKP equation [28], which also can be formulated in the dipole model [29] and CGC framework [30], [31].Odderon discovered. 9 March 2021.
