Exclusion of exotic top-like quarks with -4/3 electric charge using jet-charge tagging in single-lepton tt¯ events at CDF Academic Article uri icon

abstract

  • We report on a measurement of the top-quark electric charge in tt̄ 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-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. © 2013 American Physical Society.
