Title: Effective-Field-Theory Approach to Top-Quark Production and Decay Authors: Cen Zhang, Scott Willenbrock Abstract: We discuss new physics in top-quark interactions, using an effective field theory approach. We consider top-quark decay, single top production, and top-quark pair production. We identify 15 dimension-six operators that contribute to these processes, and we compute the deviation from the Standard Model induced by these operators. The results provide a systematic way of searching for (or obtaining bounds on) physics beyond the Standard Model.
