Odderon.

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 conformalOdderon (iny own approach, based on asymptotic theorems, included). CGC fully shows that the Pomeron- Odderon phase is an un-escapable feature of the QCD at high energies and this is, of course, really fundamental. In such a fornzulation, one can assert that the Odderon is a crucial test of QCD.

In the paper we propose and solve analytically the nonlinear evolution equation in the leading twist approximation for the odderon contribution. We found three qualitative features of this solution, which differs the odderon contribution from the Pomeron one: (i) the behavior in the vicinity of the saturation scale cannot be derived from the …The odderon in transverse spin asymmetries in elastic scattering has earlier been considered in refs. [44][45] [46], but without discussion of its operator structure. As the only nonzero function ...

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 ...Apr 1, 2019 · It's an odderon, a particle that's even more odd than its name suggests, and it may have recently been detected at the Large Hadron Collider, the most powerful atom smasher, where particles are ...

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 trust the ISR pp data to be precise enough that their comparison with the collider data ...Extracting the Odderon from. and. scattering data.

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.

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 …The U.S. Department of Energy's Office of Scientific and Technical InformationThe name ~Odderon" was invented. 9 The Odderon naturally arises in QCD (LLA) as a compound state of 3 regge- ized ghons 10 Minimal Odderon-pole finked to 3 ghon exchange, leading to a quantita- tive prediction of A(d~/dt) ~ 0 at ISR energies 11 ExperlmeEtal discovery of A(ddt) 0 at vr~ = 52.8 GeV in the structure region (It[ _ 1.3 GeV2) I ...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].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 ...In the case of odderon in [8] the intersection of the leading gluonic trajectory with C = − 1 with q q ¯ trajectories does not take place, since ρ, ω trajectories have much larger intercepts, and the resulting odderon intercept in [8] obtained using the 3 − − glueball mass and assumed slope of (2 π σ adj) −1 was predicted around −1.5.latter two it is expected that the dominant exchange is the nonperturbative odderon [1], the C= P= −1 partner of the pomeron [2]. It has been shown [3] that the suppression of the odderon contribution in pp (p¯p) scattering can be explained by diquark clustering in the proton, provided the diquark is sufficiently small ≤ 0.3 fm.

Odderon (O) [11{15], although its existence is not established yet experimentally (b). Exchanges of the pseudoscalar (PS) (ˇ0; ) and scalar (S) (a 0;f 0) mesons are considered in the tchannel (c). The direct ˚-meson radiations in the sand uchannels via the proton and its resonances are also available (dand e). In what follows, the explicit ...Odderon exchange dominates except at very small transverse momentum, and we find a cross section of about 20 nb at a centre-of-mass energy of 20 GeV. This result is compared with what is currently ...We propose to study an odderon exchange in the "pure" processes γγ→MM′, γγ→M jet, ep→eMp (M=π 0, η, η′, η c, etc. Corresponding cross sections with the "bare" odderon as the reggezied three-gluon exchange are estimated.At HERA energies in the process ep→e0 − p one should observe a steep growth (by an order of magnitude) of the "odderon" cross section.May 15, 2020 · The odderon amplitude without spin-flip falls off with decreasing diquark radius.

It is worth noting that none of these parametrizations con- tains an odderon contribution, and adding the exchange of the Odderon in addition to ...

The perturbative QCD odderon exists in two different states. The first one was proposed as the \(C=-1\) eigenstate of the Hamiltonian for three reggeized gluons (the simplest of the series of the so-called BKP states [1,2,3]).Its properties and conformal invariance were discussed very long ago [4, 5].After several attempts to numerically …Title: Physics with intact protons at the LHC: from the odderon discovery to the sensitivity to beyond standard model physics Authors: C.

In the more rigorous language of QCD, an Odderon exchange is usually associated with a quarkless odd-gluon (e.g. three-gluon, to the lowest ...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 describe an analysis comparing the p p ¯ elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in p p collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV using a model-independent approach. The TOTEM cross sections, extrapolated to a center-of …We find that the odderon amplitude increases as x decreases from 0.1 to 0.01.

After almost half a century of research, a team of Hungarian and Swedish scientists discovered the existence of the Odderon, an extremely fleeting particle. Researchers from the Wigner Research Centre for Physics, the Hungarian University of Agriculture and Life Sciences, Eötvös Loránd University, and the Swedish ...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 …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 … See more

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.

Now, a Swedish-Hungarian research group has discovered the mythical particle with the help of extensive analysis of experimental data from the Large Hadron Collider at CERN in Switzerland. We compare the purely diffractive contribution (odderon-pomeron fusion) to the photoproduction contribution (photon-pomeron fusion).

After the advent of QCD, however, theorists showed that QCD not just allowed but required the existence of such a three-gluon compound.
