Beschreibungen/Notizen

• This paper reports inclusive and differential measurements of the t t ¯ charge asymmetry A C in 20.3 fb - 1 of s = 8 T e V p p 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 t t ¯ system. The t t ¯ pairs are selected in the single-lepton channels ( e or μ ) with at least four jets, and a likelihood fit is used to reconstruct the t t ¯ event kinematics. A Bayesian unfolding procedure is performed to infer the asymmetry at parton level from the observed data distribution. The inclusive t t ¯ charge asymmetry is measured to be A C = 0.009 ± 0.005 (stat. + syst.). The inclusive and differential measurements are compatible with the values predicted by the Standard Model.
