Abstract

Non-perturbative QCD effects from Parton Distribution Functions (PDFs) may be constrained by using high-statistics Large Hadron Collider (LHC) data. Drell-Yan (DY) measurements in the Charged Current (CC) case provide one of the primary means to do this, in the form of the lepton charge asymmetry. We investigate here the impact of measurements in Neutral Current (NC) DY data mapped onto the Forward-Backward Asymmetry (AFBA_{\rm FB}) on PDF determinations, by using the open source fit platform {\tt{xFitter}}. We demonstrate the potential impact of AFBA_{\rm FB} data on PDF determinations and perform a thorough analysis of related uncertainties.
