Abstrakt: A brief overview of recent work of the CTEQ group on global QCD analysis of the parton structure of the nucleon is presented. A detailed study of the stability of predictions of parton distribution functions (PDFs) in NLO global analysis is investigated. Two topics on flavor dependence of PDFs are touched upon: (i) status of d(x)/u(x) at large x; and (ii) charge asymmetry in the strangeness sector of nucleon structure (s(x) ≠ s(x)). All three issues involve interaction between large and small x physics. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]
