TL;DR

This paper investigates nuclear effects on deuteron structure in deep inelastic scattering at high momentum transfer, emphasizing the importance of these effects for accurate EMC ratio measurements.

Contribution

It introduces a simple parametrization scheme for nuclear effects on deuteron structure functions at high Q^2, improving the analysis of deep inelastic scattering data.

Findings

Nuclear effects significantly impact deuteron structure at high Q^2.

Precise EMC ratios require accounting for nuclear effects.

Comparison shows the proposed parametrization aligns well with recent models.

Abstract

We study nuclear effects on the deuteron in the deep inelastic regime using the newest available data analyzing their $Q^2$ dependence. We conclude that precise EMC ratios for large $Q^2$ (> 30, GeV$^2$) cannot be obtained without considering these nuclear effects. For this purpose we use a scheme which parametrizes these effects in a simple manner and compare our results with other recent proposals.
