Dynamics of Anti-Proton -- Protons and Anti-Proton -- Nucleus Reactions

TL;DR

This paper reviews simulation results of anti-proton interactions with protons and nuclei using the Geant4 FTF model, which incorporates quark-gluon string dynamics to match experimental data on strange particle production.

Contribution

It demonstrates the effectiveness of the Geant4 FTF model in simulating anti-proton interactions and reproducing experimental results, especially for strange particle yields.

Findings

Model accurately describes strange particle production

Successful reproduction of Lambda hyperons and K mesons data

Uses Quark-Gluon-String Model assumptions

Abstract

A short review of simulation results of anti-proton-proton and anti-proton-nucleus interactions within the framework of Geant4 FTF (Fritiof) model is presented. The model uses the main assumptions of the Quark-Gluon-String Model or Dual Parton Model. The model assumes production and fragmentation of quark-anti-quark and diquark-anti-diquark strings in the mentioned interactions. Key ingredients of the model are cross sections of string creation processes and an usage of the LUND string fragmentation algorithm. They allow one to satisfactory describe a large set of experimental data, especially, a strange particle production, Lambda hyperons and K mesons.
