Top quark differential distributions in the SMEFT

Abstract

We discuss top quark processes, in particular $tW$ production and top-antitop pair production, as probes of dimension-6 Standard Model Effective Field Theory (SMEFT). We calculate top-quark double differential distributions in transverse momentum and rapidity, and we perform SMEFT fits at LO, NLO and, by adding second-order soft-gluon corrections, at approximate NNLO.
