Odderon

Odderon in QCD. Gian Paolo Vacca. 2001. A review on how the Odderon idea does appear in QCD is given. In the last years it has been developed a non-perturbative QCD approach based on the stochastic vacuum model and a perturbative one based on resummation techniques in the small x QCD region. Last developments on the perturbative analysis are ....

The trajectory intercept is clearly smaller than the pomeron and even the {omega} trajectory's intercept which provides an explanation for the nonobservation of the ...

The odderon was initially predicted in 1973 as a composite state of three reggeized gluons, based on the asymptotic theorem proposed by L. Lukaszuk and B. Nicolescu [10]. In detail, the odderon contributes to scattering amplitude by decomposing the amplitude into parts associated with charge-conjugation exchanges, specificallyC= +1 for the pomeron and …The odderon is now a fundamental object in QCD and it has to be found experimentally if QCD is right. In the present paper, 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 and moderate t. ….

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 ...In December 2020, the D0 and TOTEM Collaborations made public the odderon discovery based on a purely data driven approach in a CERN and Fermilab approved preprint that was later published in Physical Review Letters. In this experimental observation, the TOTEM proton-proton data in the region of the diffractive minimum and maximum was …

We study Pomeron-Odderon interference effects giving rise to charge and single-spin asymmetries in diffractive electroproduction of a pair. We calculate these asymmetries, originating from both ...Spin-dependent Pomeron and Odderon in elastic proton-proton scattering. We introduce a new model of near-forward elastic proton- (anti)proton scattering at high energy based on the modern formulation of Pomeron and Odderon in terms of Wilson lines and generalized TMDs (GTMDs).

Kalb-Ramond two -form, B, and its Regge intercept at strong coupling was derived.

A direct way to probe the Odderon in elastic scattering is by comparing the differential cross-section of particle– particle and particle–antiparticle scattering at sufficiently high energies [3,4].Discovery of the odderon.

A simple new form of the trajectories, with threshold and asymptotic behaviour required by analyticity and unitarity, is proposed.

I'm only just starting to research into antimatter as I find it really interesting, but I came across a way of visualising matter and antimatter as bumps and 'ditches' in an otherwise flat plane of the electron field. However, when the matter and antimatter annihilate, two bumps are created in the electromagnetic plane.We study the rapidity dependence of the central exclusive production cross sections of C-even mesons in pA and AA collisions, where A is a heavy ion. We observe qualitatively different behaviour of the contributions arising from \(\gamma \)-Odderon and Pomeron-Pomeron fusion mechanisms.This can be used to extract the Odderon signal from the events of \(f_2\) mesons exclusively produced in ...
