Three Pomerons versus D0 and TOTEM data

Abstract

This paper highlights the predictive power of the three-component Pomeron model designed by the authors ten years ago, with a partial account of the multiplicity of Pomerons in QCD. The model is put to the test by comparing its predictions with the recent data from the D0 and TOTEM collaborations at 1.96 and 7 TeV, respectively. We also compare model predictions for inelastic cross sections to experimental measurements by the TOTEM, CMS, ALICE, and ATLAS collaborations. It is shown that the D0 data are perfectly predicted by the model. Total, elastic, and inelastic cross-section predictions are in agreement with the measurements by the TOTEM, CMS, ALICE, and ATLAS collaborations. Differential cross-section data at 7 TeV show slight disagreement with predictions of the model in the high-$t$ region. Discussions on the origin of the disagreement and conclusions are presented.
