The Top-Quark Charge Asymmetry with a Jet Handle

Top-quark physics provides us with a portal to potential physics beyond the Standard Model. To date, the only evidence of an anomaly in top-quark physics is the large forward-backward asymmetry observed at the Tevatron. Shedding light on this anomaly by measuring a charge asymmetry at the LHC, however, is a difficult endeavor. I will discuss the prospects to observe a charge asymmetry in top-antitop production in association with an energetic jet. This "jet handle" can further help to discriminate between new-physics scenarios that attempt to explain the Tevatron anomaly.
