TL;DR

This paper presents a quark-diquark based model for simulating diffraction dissociation in hadron interactions, comparing its predictions with experimental data and other models across various energies and particle distributions.

Contribution

It introduces a novel low mass diffraction dissociation model using quark-diquark representation and applies the Glauber-Gribov framework for hadron-nucleus interactions.

Findings

Model agrees with experimental mass spectra of nucleon-pion systems.

Predictions match experimental data for hadron-nucleus cross-sections.

Secondary particle distributions are well described across energy ranges.

Abstract

A low mass single diffraction dissociation mode based on the quark-diquark representation of hadron-nucleon interaction is proposed. The mass spectra of nucleon-pion system are compared with experimental data and predictions of other models. The hadron-nucleus single-diffraction cross-sections are calculated in the framework of the Glauber-Gribov model for integral cross-sections. The model predictions are compared with experimental data for the different distributions of secondary particles produced in the hadron-nucleus interactions in the momentum range 31-320 GeV/c.
