Odderon.

In other words we consider a QCD Odderon with intercept α Odd (0) = 1, as was obtained in [22], and normalization given by the parameter σ Odd. The simplified lowest α s calculation leads to σ Odd = 0.8 mb [23]. With such a small coupling of O (1 mb) the Odderon is almost invisible in Fig. 2. Recall that, for α Odd (0) = 1, Odderon ...Dec 21, 2022 · In this work, we propose that the odderon is a reggeized odd-glueball tensor spin-3. To demonstrate our proposal, we study the and elastic scattering by including contributions of the spin-3 odderon and spin-2 pomeron exchange in the process. The phenomenological effective Lagrangian approach is used to calculate the and elastic scattering ... 22 Aug 2023 ...

The Odderon is now a fundamental object in QCD and CGC and it has to be found experimentally if QCD and CGC are right. In the present talk, 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 ...The Odderon is described by the Bartelsâ€"Kwiecinskiâ€"Praszalowicz (BKP) equa- n [3], which resums terms of the order α s (α s log s) n with arbitrary n in which three gluons in C =âˆ'1 state are exchanged in the t -channel.

1 The Odderon is the odd-signature (C =−1) partner of the even-signature (C = 1) Pomeron, see for reviews [5-7]. It is a firm prediction of QCD [8,9], but so far the experimental evidence for its existence is not definitive. There have been various proposals on how to search for Odderon-exchange effects in high energy collisions. In ...

No π 0 signal is observed and an upper limit on the ...Inspired by the evidence of the odderon exchange recently observed by the D0 and TOTEM Collaborations, a quantum chromodynamics (QCD) sum rule investigation is performed to study the odderon as a three-gluon bound state. There may exist six lowest-lying three-gluon odderons with the quantum numbers J P C =1 /2 /3 ±- . We systematically construct their interpolating currents, and calculate ...CERN's Large Hadron Collider confirms the discovery of the "odderon", a subatomic compound of three gluons that forms when protons collide violently but aren't destroyed; the odderon was theorized in the early 70s and finally detected

We summarize the results of including running coupling corrections into the nonlinear evolution equation for diffractive dissociation. We also document a prediction that the NLO QCD odderon intercept is zero resulting from a discussion at the Diffraction 2012 Workshop.Odderon is a cousin of Pomeron which emerged already about half century ago in the so called Regge theory to explain the logarithmically rising (rather than decreasing) cross sections in proton ...Foto: CERN.

The Odderon consists of three gluons. Gluons "glue" the quarks together to "hadrons", particles that are held together by the strong interaction, like the proton and the neutron. Gluons are the mediators of the strong interaction between quarks in a similar way as the photon, the particle which light is made of, is ...

The odderon would be expected to contribute with different signs to pp and pp̄ scattering. Supporting this picture, the two data sets disagree at the 3.4σ level, providing evidence for the t-channel exchange of a colorless, C-odd gluonic compound.The odderon amplitude without spin-flip falls off with decreasing diquark radius.

3.1 Conformal Pomeron, Odderon and Analyticity At high-energy, analyticity and crossing lead to C = 1 vacuum exchanges, the Pomeron and the Odderon. 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 conformalWe consider the reaction γp → π + π − p at high energies. Our description includes dipion production via the resonances ρ, ω, ρ ′ and f 2, and via non-resonant mechanisms. The calculation is based on a model of high energy scattering with the exchanges of photon, pomeron, odderon and reggeons.

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.

The authors report an odderon Regge trajectory emerging from a field theoretical Coulomb gauge QCD model for the odd signature J{sup PC} (P = C = -1) glueball states (oddballs).
