ABSTRACT
This paper reports inclusive and differential measurements of the [Formula see text] charge asymmetry [Formula see text] in [Formula see text] of [Formula see text][Formula see text] collisions recorded by the ATLAS experiment at the Large Hadron Collider at CERN. Three differential measurements are performed as a function of the invariant mass, transverse momentum and longitudinal boost of the [Formula see text] system. The [Formula see text] pairs are selected in the single-lepton channels (e or [Formula see text]) with at least four jets, and a likelihood fit is used to reconstruct the [Formula see text] event kinematics. A Bayesian unfolding procedure is performed to infer the asymmetry at parton level from the observed data distribution. The inclusive [Formula see text] charge asymmetry is measured to be [Formula see text] (stat. [Formula see text] syst.). The inclusive and differential measurements are compatible with the values predicted by the Standard Model.
