High-energy single diffractive dissociation of nucleons and the 3P-model applicability range

TL;DR

This paper evaluates the applicability of the 3P-model for high-energy single diffractive nucleon dissociation, highlighting the significance of secondary Reggeon exchanges up to Tevatron energies based on experimental data analysis.

Contribution

It provides a critical assessment of the 3P-model's validity range using recent experimental data, including CMS results, and emphasizes the role of secondary Reggeon exchanges.

Findings

The 3P-model's approximation is valid within a certain energy range.

Secondary Reggeon exchanges significantly contribute up to Tevatron energies.

Recent CMS data helps reliably estimate the triple-Pomeron coupling.

Abstract

The adequacy of the triple-Pomeron interaction approximation (the 3P-model) for description of the high-energy single diffractive dissociation of nucleons is analyzed via application to the available experimental data on nucleon-nucleon scattering, including the recent results produced by CMS Collaboration which allow to estimate reliably the triple-Pomeron coupling value. It is argued that the total contribution of secondary Reggeon exchanges is not negligible up to the Tevatron energy.
