Abstract: Various measurements provided by the ATLAS collaboration have significant impact on parton density functions. Inclusive production of W and Z bosons have been analysed using an NNLO QCD fit and found to constraint the strange­quark density at medium and low Bjorken­x. The inclusive jet production at different centre­of­mass energies, measured by ATLAS are used in an NLO QCD fit and show impact for the gluon density. Off­resonance Drell Yan production may be used to constrain anti­quark density at high x. The measurements have higher impact when they are used in a common fit, taking into account correlations of the systematic uncertainties.
