  • Mô tả: This paper reports inclusive and differential measurements of the [Formula omitted] charge asymmetry [Formula omitted] in [Formula omitted] of [Formula omitted] [Formula omitted] 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 omitted] system. The [Formula omitted] pairs are selected in the single-lepton channels (e or [Formula omitted]) with at least four jets, and a likelihood fit is used to reconstruct the [Formula omitted] event kinematics. A Bayesian unfolding procedure is performed to infer the asymmetry at parton level from the observed data distribution. The inclusive [Formula omitted] charge asymmetry is measured to be [Formula omitted] (stat. [Formula omitted] syst.). The inclusive and differential measurements are compatible with the values predicted by the Standard Model.
