Exclusion of exotic top-like quarks with -4/3 electric charge using jet-charge tagging in single-lepton t[¯ over t] events at CDF
We report on a measurement of the top-quark electric charge in tt̅ events in which one W boson originating from the top-quark pair decays into leptons and the other into hadrons. The event sample was collected by the CDF II detector in √s=1.96 TeV proton-antiproton collisions and corresponds to 5.6...
