Actually, we first consider the anomalous Odderon. The odderon, the counterpart of the pomeron that carries odd charge parity was introduced in 1973 by Leszek Łukaszuk and Basarab Nicolescu.

2019-04-10 · For this purpose, we employ an effective Lagrangian approach by using the tree-level Born approximation, and various experimental and theoretical inputs. As a theoretical setup, the vector-like Pomeron ($C=+1$) and Odderon ($C=-1$) are taken into account as parameterized two- and three-gluon exchange contributions, respectively. Pomeron is a Reggeon with the intercept close to 1. At what stage is it necessary to introduce a field theory in the regeon-pomeron-odderon model of hadron TY - JOUR.

We establish the existence of a fixed point and its universal properties, which exhibits a novel symmetry structure in the space of Odderon-Pomeron interactions. As in our previous analysis, this part of our program aims at the Protons are made up of quarks and gluons, that briefly form Odderon and Pomeron particles.

In the conformal limit, both the weak-coupling BFKL Pomeron and Odderons correspond to J-plane branch points, e.g., the BFKL Pomeoron is a cut at j(+) 0 When it’s an even-numbered group of gluons (two, four, etc.), we call it a pomeron. When the number of gluons in the group is odd (three, five, etc.), well, you guessed it: That’s an odderon. We consider the first LHC data for pp collisions in the framework of Regge theory. The integral cross sections and inclusive densities of secondaries are determined by the Pomeron exchange, and we present the corresponding predictions for them. The first measurements of inclusive densities in midrapidity region are in agreement with these predictions.

Pomeron - Pomeron - qaz.wiki

odderon (plural odderons) The hypothetical counterpart of the pomeron, carrying odd charge parity. Translations . Pomerons and odderons At low energies, differences in pp vs pp̄ scattering are due to the exchange of different virtual mesons. At multi-TeV energies, on the other hand, proton interactions are expected to be mediated purely by gluons.
