<div class="">Title: Deuteron Scattering Experiments in CTEQ-JLab and CTEQ-TEA Global QCD Analyses and Monte-Carlo pdf error set</div>
<div class="">Abstract: Experimental measurements in deep-inelastic scattering and lepton-pair production on deuterium targets play an important role in the flavor separation of $u$ and $d$ (anti)quarks in global QCD analyses of the parton distribution functions
(PDFs) of the nucleon. I investigate the impact of theoretical corrections accounting for the light-nuclear structure of the deuteron upon the fitted $u, d$-quark, gluon, and other PDFs in the CJ15 and CT18 families of next-to-leading order CTEQ global analyses.
The investigation is done using the $L_2$ sensitivity statistical method, which provides a common metric to quantify the strength of experimental constraints on various PDFs and ratios of PDFs in the two distinct fitting frameworks. In addition, I will also
present some new results on the generation of the Monte-Carlo replicas, and discuss its connection with the Hessian representation in the in the framework of $L_2$ sensitivity.</div>
