Abstract
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 fb[superscript -1]. We find the data to be consistent with the standard model and exclude the existence of an exotic quark with -4/3 electric charge and mass of the conventional top quark at the 99% confidence level.
