Measurements of the forward-backward asymmetry in neutral-current Drell-Yan di-lepton production have primarily been used for determinations of the weak mixing angle $\theta_W$.
We investigate the possibility of using the reconstructed forward-backward asymmetry to place constraints on the determination of the parton distribution functions (PDFs). We perform this study using the open-source QCD platform xFitter. We explore the constraints on the flavour structure of quark distributions and the role of appropriate selection cuts on lepton rapidities both near the Z-boson peak and away from it.
