Effective field theory approach to top-quark physics at NLO accuracy
Cen Zhang (Université Catholique de Louvain)

Top quark processes potentially suffer from a large uncertainty at leading order in QCD. To search for new physics in top quark processes, it is desirable to have a model-independent approach at the NLO accuracy. Effective field theory provides a framework in which the radiative corrections to new interactions can be consistently included, but the analysis can be complicated due to operator mixing effects. I will discuss the effective field theory approach to top-quark physics, with a focus on NLO calculation. In particular I will present its applications in precision electroweak tests, in top-quark decay processes and in top-quark FCNC production.
