The observation of charge asymmetry of pions at moderate M_{pi+pi-} will be an undoubted signal of odderon existence.

Using a model with mildly energy dependent form factors as input and performing full eikonalization before we compare with the data, the answer that we find from a careful examination of the various options is that the odderon is indeed necessary if: 1) we ...Oct 25, 2005 · 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. It has been argued that saturation/CGC effects tend to decrease the Odderon intercept, possibly providing an explanation for the lack of experimental evidence for the Odderon so far. We study the effects of a parity-odd ``odderon'' correlation in Jalilian-Marian--Iancu--McLerran--Weigert--Leonidov--Kovner renormalization group evolution at high energy. Firstly we show that in the eikonal picture where the scattering is described by Wilson lines, one obtains a strict mathematical upper limit for the magnitude of the odderon amplitude compared to the parity-even Pomeron one.Odderon and seven Pomerons: QCD Reggeon field theory from JIMWLK evolution . × Close Log In.

In our numerical analysis we find that the fixed cut solution with intercept one persists, hinting at a physical Odderon with intercept one and a small t-slope.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 ...The differential cross-section for elastic pp (left panel) and p ¯ p (right panel) scattering obtained after the substitution of the C = −1 amplitude in [16] by the calculated odderon amplitude ...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 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.In other words, we look for and find a robust Odderon signature in the difference of the scaling functions of the elastic differential cross-section between pp and \(p\bar{p}\) collisions. We thus discuss the Odderon features that can be extracted in a model-independent manner by directly comparing the corresponding data sets to one another.The odderon amplitude without spin-flip falls off with decreasing diquark radius.

The implications of these data for Odderon (odd ...The odderon intercept appeared to be smaller than unity, meaning that C-odd amplitudes should decrease with energy. In a following analysis, however, it was discovered by Bartels, Lipatov and Vacca (BLV) [19] that the normalizability condition of the holomorphic wave functions may be relaxed, leading to a new odderon solution, having a flat overall …The odderon, being odd under charge conjugation, couples with different signs to protons and antiprotons and can hence account for that difference.

Exchanging an even number of gluons is a crossing-even part of elastic proton-proton and proton-antiproton scattering, while odderon exchange ...v. t. e. In particle physics, a glueball (also gluonium, gluon-ball) is a hypothetical composite particle. [1] It consists solely of gluon particles, without valence quarks. Such a state is possible because gluons carry color charge and experience the strong interaction between themselves. Glueballs are extremely difficult to identify in ...The odderon is a particle made up of three gluons, which are the carriers of the strong force that holds atoms together. This is the first time scientists have found experimental evidence for the existence of the odderon, making it a major discovery in physics. 107. Rik07 • 1 mo. ago.2.2.. Evolution equationIt is now straightforward to write down an evolution equation for the odderon in the dipole model. We have shown above that in the dipole model a single step of the small-x evolution for the odderon is the same as for the BFKL pomeron [19].Subsequent steps of the dipole evolution would generate more color dipoles in the onium wave function.We study the Odderon contribution to elastic pp and ppbar scattering at high energies.
