To that end we replace their triple-gluon exchange amplitude by one of the model odderon contributions. We retain the original parameter values of the fit and make no attempt to improve it. 2.2. A position-space model

In the case of nuclear targets, the Odderon cross section becomes enhanced thanks to the mass number of the nuclear target. The gluon saturation effect induces a shift in the diffractive pattern with respect to the Primakoff process that could be used as a signal for the Odderon.Sep 9, 2022 · In this short report, we will study elastic interactions at high energies in order to obtain evidence for the existence of the odderon [].Elastic \(pp\) and \(p\bar{p}\) scattering corresponds to \(pp\rightarrow pp\) and \(p\bar{p}\rightarrow p\bar{p}\) where the protons and antiprotons are intact after interaction, scattered at very small angle and measured in dedicated detectors called roman ...
