Jet Charge with the ATLAS Detector using $\sqrt{s}=8$ TeV $pp$ Collision Data

Abstract: The momentum-weighted sum of the charges of tracks associated to a jet provides an experimental handle on the electric charge of fundamental strongly-interacting particles. An overview of a study of this jet charge observable for jets produced in dijet and semileptonic $t\bar{t}$ events using $5.8$ $\mathrm{fb}^{-1}$ of data with the ATLAS detector at $\sqrt{s}=8$ TeV is described here. In addition to providing a constraint on hadronization models, jet charge has many possible applications in measurements and searches. The modelling of jet charge and its performance as a charge-tagger are studied in order to establish this observable as a tool for future physics analyses.
