Uncertainties in the parametrization of Parton Distribution Functions (PDFs)are becoming a serious limiting systematic uncertainty in Large Hadron Collider(LHC) searches for Beyond the Standard Model physics. This is especially truefor measurements at high scales induced by quark and anti-quark collisions,where Drell-Yan continuum backgrounds are dominant. Tools are recentlyavailable which enable exploration of PDF fitting strategies and emulate theeffects of new data in a future global fit. ePump is such a tool and it isshown that judicious selection of measurable kinematical quantities can reducethe assigned systematic PDF uncertainties by significant factors. This will bemade possible by the huge statistical precision of future LHC Standard Modeldatasets.
