High order radiative corrections for unpolarized electron proton elastic scattering at low $Q^2$

TL;DR

This paper examines the significance of high order radiative corrections in unpolarized electron-proton elastic scattering at low $Q^2$, highlighting their impact beyond the lowest order calculations especially at larger momentum transfers.

Contribution

It provides a detailed analysis of high order radiative corrections and their influence on experimental data interpretation in electron-proton scattering.

Findings

Higher order corrections become significant for $Q^2$ larger than the electron mass.

Radiative corrections exhibit notable dependence on the parameter $psilon$.

Corrections at higher orders alter the interpretation of scattering data.

Abstract

We investigate the effect of high order radiative corrections in unpolarized electron proton elastic scattering and compare with the calculations at lowest order, which are usually applied to experimental data. We show that higher order terms play a role, starting from values of the momentum transfer squared, $Q^2$, larger than the electron mass. Particular attention is devoted to the $\epsilon$ dependence of radiative corrections.
