Geant4 Electron–Proton Integral Inelastic Cross Section Models

Electron–proton integral inelastic cross Section is calculated based on the proton structure function formalism. The cross section is compared with the Geant4 CHIPS model calculations using the equivalent photon method (EPM).

I. Introduction

The inelastic interactions of leptons with hadrons, especially electrons with protons, provide a unique method for investigation of the hadron structure. For the simulation of the process intensity, one needs the integral inelastic cross sections defining the mean free path of the process.
