We investigate charm production in charged-current deep-inelastic
scattering (DIS) using the xFitter program. xFitter is an open-source
software framework for the determination of PDFs and the analysis of
QCD physics, and has been used for a variety of LHC studies. The
study of charged current DIS charm production provides an important
perspective on the strange quark PDF, s(x). We make use of the
xFitter tools to study the present s(x) constraints, and then use
LHeC pseudodata to infer how these might improve. Furthermore, as
xFitter implements both Fixed Flavor and Variable Flavor number
schemes, we can examine the impact of these different theoretical
choices; this highlights some interesting aspects of multi-scale
calculations. This study provides a practical illustration of the
many features of xFitter.
