Inclusive electron spectrum in the region of pion production in electron-nucleus scattering and the effect of the quasi-elastic interaction

TL;DR

This paper models inclusive electron scattering off oxygen, incorporating quasielastic, delta, and non-resonant pion production mechanisms, achieving good agreement with experimental data across a broad energy range.

Contribution

The authors extend existing quasielastic scattering formalism to include delta and non-resonant pion production, providing a comprehensive model for electron-nucleus scattering.

Findings

Model agrees well with experimental data across energy range

Includes both delta and non-resonant pion production mechanisms

Accurately describes the dip region between quasielastic peak and resonance

Abstract

We have carried out a calculation of the inclusive electron scattering cross section off oxygen in the kinematical region corresponding to beam energies between 700 and 1200 MeV, where quasielastic scattering and single pion production are the dominant reaction mechanisms. The formalism developed and successfully applied to describe quasielastic scattering has been extended to include both delta production and non-resonant pion production. The results are in fairly good agreement with experimental data over the whole range of energy transfer, including the dip region between the quasielastic peak and the first resonance.
