We show that the asymmetry in the fractional energy of charm versus anticharm jets produced in high energy diffractive photoproduction is sensitive to the interference of the Odderon (C = {minus}) and Pomeron (C = +) exchange amplitudes in QCD. We predict the dynamical shape of the asymmetry in a simple model and estimate its magnitude to be of the order 15% using an Odderon coupling to the ...Mar 16, 2021 · Ginebra, 16 mar (EFE).- El Centro Europeo de Física de Partículas (CERN) anunció hoy el descubrimiento del odderón, una rara combinación de tres partículas fundamentales llamadas gluones que había sido mencionada en teorías hace casi 50 años pero que no había podido identificarse hasta ahora en condiciones reales. "The odderon is a solid prediction of the theory of strong interactions, made almost half a century ago," said physicist Yuri Kovchegov from The Ohio State University, who was not involved in the new work.

Obviously, odderon operator changes sign when exchanging the transverse positions of two Wilson lines. As a consequence odderon contribution is the k⊥-odd part of the dipole amplitude in momentum space. Motivated by this observation, one can alternatively identify odderon contribution by parameterizing dipole amplitude in the following way, Z ...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....

Odderons exist in QCD as a compound state of three reggeized gluons. Potentially theorized in 2015. It was potentially observed only in 2017 by the TOTEM experiment at the LHC.The odderon amplitude without spin-flip falls off with decreasing diquark radius.

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.

(CERN) Through painstaking work, scientists have found evidence of a quasiparticle that was first imagined as a hypothesis almost 50 years ago: the odderon. The odderon is now a fundamental object in QCD and it has to be found experimentally if QCD is right. In the present paper, we show how to find it at RHIC and LHC. The most spectacular signature of the odderon is the predicted difference between the differential cross-sections for proton–proton and antiproton–proton at high s and moderate t. This …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]. The Pomeron is ...Secondly, the Odderon has recently been shown to naturally emerge from the Color Glass Condensate (CGC), a theory for the high-energy asymptotics of QCD.
