Contribution

It provides a combined analysis of two-photon exchange effects and QCD corrections on deuteron structure functions in elastic scattering.

Two-photon exchange effects significantly affect structure factors.

QCD logarithmic corrections modify observable quantities.

Results improve the theory-data agreement in deuteron scattering.

Abstract

The aim of this work is to investigate the simultaneous influence of two-photon effects in quantum electrodynamics (QED) and logarithmic corrections in quantum chromodynamics (QCD) on certain observable experimental quantities (structure factors $A$ and $B$) in elastic electron-deuteron scattering. Analyzing these effects broadens our understanding of particle physics, particularly the manifestations of quark-gluon degrees of freedom in the deuteron. Keywords: elastic electron-deuteron scattering, structure of the deuteron, deuteron structure functions, QCD, QED, quark, gluon, two-photon exchange effects, theory-data comparison.
