The charm production at LHeC and it's potential on probing the strange content of the proton

The charm production in charged-current deep-inelastic scattering (DIS) using the xFitter frame-work has been studied. Recent results from the LHC have focused renewed attention on the determination of the strange-quark parton distribution function (PDF), and the DIS charm process provides important complementary constraints on this quantity. The modern PDF uncertainty and the LHeC pseudodata are used to investigate the potential improvement of the LHeC proposed facility. As xFitter implements both fixed-flavor-and variable-flavor-number schemes, we can compare the impact of these different theoretical choices; this highlights some interesting aspects of multi-scale calculations. We find that the high-statistics LHeC data covering a wide kinematic range could substantially reduce the strange PDF uncertainty.
