Constraining Parton Distribution Functions from Neutral Current Drell-Yan Measurements

Abstract

We study the cross section σand Forward-Backward asymmetry A_{FB} in the process pp \to γ^*,Z \to \ell^+\ell^- (with \ell=e,μ) for determinations of Parton Distribution Functions (PDFs) of the proton. We show that, once mapped in the invariant mass of the di-lepton final state, M({\ell\ell}), both observables, σand 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 quark PDFs over a sizeable (x,Q^2) range.
