The qualitative picture for Pomeron exchange in weak coupling [10] has been understood for a long time, in leading order expansion in g 2 YM and all order sum in g YM log(s=s 0). In the conformal We compute the transverse single spin asymmetry in forward p ↑ p → h X and p ↑ A → h X collisions from the odderon mechanism originally suggested by Kovchegov and Sievert [Phys. Rev.

In ...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 ...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.Illustration: Benjamin Currie/Gizmodo.

Odderon. 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 ...In 1973 the Odderon concept was pushed forward [] which embodies a hypothesis that the leading C-even agent dominating high energy behaviour of the strong interaction cross-sections, the famous Pomeron, may have a C-odd counterpart which can give non-negligible contributions at high energies in contrast to secondary Reggeons \( \rho ,\omega \) etc rapidly dying off with the energy growth.The odderon, on the other hand, has much more subtle signatures. This has made the hunt for the odderon so much more challenging.'' Top image: The TOTEM experiment's "Roman Pot" detectors in the Large Hadron Collider tunnel. Credit: CERN.

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). 2 Searching for evidence of Odderon exchange Although in QCD we expect both Pomeron and Odderon exchange to contribute to scattering processes, the pre{LHC experimental quest for the Odderon has proven to be quite a challenging task, see for instance [22,24,25,30] for reviews. In particular, the contribution from Odderon
3.1 Conformal Pomeron, Odderon and Analyticity At high-ene 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.

Version published in EPJC containing extra references The Odderon remains an elusive object, 33 years afterDOI: 10.1016/0370-2693(90)91756-2 Corpus ID: 120 The odderon exchange contribution is calculated in nonperturbative QCD, using functional integral techniques and the model of the stochastic vacuum. For the proton we assume a quark-diquark structure as suggested by the small odderon amplitude in pp and pp forward scattering. We show that odderon exchange leads to a much larger inelastic than ...If the odderon didn't exist, then DZero and TOTEM should have seen the same scattering patterns in their data after adjusting for the energy differences between the Tevatron and LHC. But no matter how they processed the data, the scattering patterns remained distinct. "We did many cross checks," Royon says. Here we show that in the dual description the Odderon is the Reggei By restricting to the Wandzura-Wilczek approximation, where the dynamical twist-3 PDFs are dropped, we find that the odderon contribution to the polarized cross section for inclusive hadron production is exactly zero at the next-to-leading order in the strong coupling.
