Description
We study the systematic uncertainty and possible biases introduced by theoretical assumptions needed to include DIS data at large x in a global QCD analysis. In particular, working in the CTEQ-JLab framework, we focus on different implementations of higher-twist corrections to the nucleon structure functions, and of off-shell deformations of PDF in deuteron targets, and how their interplay impacts the extraction of the d-quark PDF and the calculation of the neutron structure function at large x. The full inclusive DIS data set from JLab will be leveraged to further constrain the studied corrections.
