Description
We present recent results from the xFitter project: an open-source
software framework for the determination of PDFs and the analysis of
QCD physics. xFitter has been used for a variety of LHC studies
including the measurement of the strange PDF, which we briefly
summarize. Additionally, charged current DIS charm production provides
a complementary perspective on s(x). We make use of the xFitter tools
to study the present s(x) constraints, and then use LHeC pseudo-data
to infer how these might improve. We also make use of the LHC
forward-backward asymmetry in neutral current Drell-Yan production to
help improve the up and down distributions. These studies provide
practical illustrations of the many features of xFitter.
