Three Pomerons vs DO and TOTEM Data

TL;DR

This paper tests a three-component Pomeron model against recent high-energy collision data from DO and TOTEM, confirming its predictive power for total, elastic, and inelastic cross sections, with minor discrepancies at high momentum transfer.

Contribution

The study validates a decade-old three-Pomeron model against recent experimental data, demonstrating its accuracy in predicting various cross sections at high energies.

Findings

Model accurately predicts DO data at 1.96 TeV.

Predictions align with TOTEM, CMS, ALICE, ATLAS measurements.

Slight disagreement observed in high-$t$ differential cross sections at 7 TeV.

Abstract

This note highlights the predictive power of the 3-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 DO and TOTEM Collaborations at 1.96 and 7 TeV, respectively. We also compare model predictions for inelastic cross section to experimental measurement by TOTEM, CMS, ALICE, and ATLAS collaborations. It is shown that the DO data are perfectly predicted by the model. Total, elastic, and inelastic cross section predictions are in agreement with the measurements by TOTEM, CMS, ALICE, and ATLAS Collaborations. Differential cross section data at 7 TeV show slight disagreement with predictions of the model in high-$t$ region. Discussions on the origin of the disagreement and conclusions are presented.
