Abstract
Neither the cross section \sigma\ nor the Forward-Backward asymmetry A_{FB} in the process pp \to gamma^*,Z \to \ell^+ \ell^- (with \ell=e,\mu) are currently being exploited systematically in constraining the Parton Distribution Functions (PDFs) of (anti)quark inside the (anti)proton. We show that, once mapped in the invariant mass of the di-lepton final state, M(\ell^+ \ell^-), both observables, \sigma\ and A_{FB}, display a statistical error which is presently competitive with that assigned to the existing PDF sets and which will rapidly become smaller than the latter as the luminosity being accumulated at Run-II of the LHC grows. This statement is applicable to both on-peak and off-peak M(\ell^+ \ell^-) regions, both (just) below and above it, thereby offering a means of constraining the (anti)quark PDFs over a sizeable (x,Q^2) range.
