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.

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. The possible contribution of Odderon We consider the first LHC data for pp collisions in the framework of Regge theory.

Rev. D 99, 094038 (2019) 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 on pc {Mathematical expression} is meaningful, 2 The Pomeron exchange contributions are related to multi-gluon exchanges in QCD, which are color singlet bound state of Reggeized gluons, such as tensor glueball and Odderon. 2021-02-23 · In Ref. , a phenomenological Reggeon + Pomeron + Odderon exchange model is employed to study, in particular, the possible hollowness effect in the high-energy elastic pp collisions.

A dipole model is used for the pomeron and for the odderon. By construction, our (bare) pomeron ansatz produces a single dip, as observed experimentally.

The odderon, the counterpart of the pomeron that carries odd charge parity was introduced in 1973 by Leszek Łukaszuk and Basarab Tensor pomeron, vector odderon and diffractive produc- tion of meson and baryon pairs in proton-proton collisions.
