Description

I will present recent updates from the CTEQ-JLab (CJ) global PDF analysis. These include the effort to put together a world DIS database, the extraction of PDFs and neutron structure function F2 at large x, and the analysis of the systematic uncertainty due the interplay of higher-twist and off-shell nucleon modification in deuteron targets. I will then discuss how future experiments and facilities, especially the EIC, will improve our understanding of PDFs and nuclear effects.
