Measurements of charge and CP asymmetries in b-hadron decays using top-quark events collected by the ATLAS detector in pp collisions at s=8 TeV

Same- and opposite-sign charge asymmetries are measured in lepton+jets tt¯$$ t\overline{t} $$ events in which a b-hadron decays semileptonically to a soft muon, using data corresponding to an integrated luminosity of 20.3 fb−1 from proton-proton collisions at a centre-of-mass energy of s=8$$ \sqrt{s
