For the odderon, using Table 2 and k = 0 . 10 GeV 2 , excludingThe big hope is the discovery of the Odderon in the LHC region by measuring the phase of the amplitudes, i. e. ˆand d˙=dt. It is precisely in this context that the TOTEM datum for ˆat p s = 13 TeV is crucial. We define our Froissaron-Maximal Odderon (FMO) model, valid at t = 0 as a superposition of the Froissaron, Maximal Odderon and ...The wave function of the Odderon and other multi-gluon composite states satisfies the BKP equation. The corresponding Hamiltonian in the multi-color limit has the properties of the Möbius invariance, holomorphic separability, duality and integrability. We discuss various approaches applied to the solution of the BKP equation for the singlet ...In the leading-log approximation of QCD such a contribution arises as a sum of irreducible colorless exchanges of three gluons, with charge conjugation C= - I [2 ]. In complex angular momentum, the t=0 intercept of this odderon can be ao>- 1.

Researchers at the Large Hadron Collider have now observed what may be the first-ever experimental proof of the odderon.

For example, the study on odderon contribution based on diquark model and QCD-inspired model can be found in [48] and [49] respectively.

Comments: 19 pages, 4 figures. Version published in EPJC containing extra referencesWe 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-mass energy of √{s }=1.96 TeV , are compared with the D0 measurement in ...Evidence of the odderon. In their search for odderons, CERN researchers focused on hadrons, a family of subatomic particles that includes protons and neutrons. Hadrons are composed of two or more quarks that are held - or glued - together by elementary particles called gluons.

In the case of the odderon the wave function in impact-parameter space depends on only one anharmonic ratio and the corresponding functional is signifi- cantly simplified. We discuss in the variational approach the relation between the odderon and the pomeron in QCD. A semi- quantitative argument is given that the intercept of the odderon in ...Another odderon trajectory with 3g glueballs of Y-shape, corresponds to 11% higher masses and low intercept. These findings are in agreement with recent experimental data, setting limits on the ...Odderon (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. Yuri ...In the high energy regime of Quantum Chromodynamics (QCD) novel effective degrees of freedom, reggeized gluons, arise. They form composite states such as the Pomeron (2 reggeized gluons) and Odderon [] (3 reggeized gluons), which are understood within the Balitsky-Fadin-Kuraev-Lipatov (BFKL) approach [].Odderon exchange is described by solving the Bartels-Kwiecinski-Praszalowicz (BKP ...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 Chromodynamics (QCD).

The odderon is not a fundamental particle but a very rare state of three gluons. Reply Breaca ...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 ...The odderon, on the other hand, has much more subtle signatures.
