Systematic uncertainty of offshell corrections and higher-twist contribution in DIS at large x

High Energy Physics - Phenomenology 2024-07-08 v1 High Energy Physics - Experiment Nuclear Theory

Abstract

We study the systematic uncertainty and biases introduced by theoretical assumptions needed to include large-xx DIS data in a global QCD analysis. Working in the CTEQ-JLab framework, we focus on different implementations of higher-twist corrections to the nucleon structure functions and of offshell PDF deformations in deuteron targets and discuss how their interplay impacts the extraction of the dd-quark PDF and the calculation of the neutron structure function at large xx.
