报告摘要：

Standard Model Effective Field Theory provides an efficient way for characterizing and analyzing physics beyond the Standard Model.  I will discuss its application in top-quark physics at the LHC.  Topics will include common standards for the interpretation of top-quark measurements, the status and plans for NLO predictions in the form of automatic event generator and Monte Carlo simulation, and phenomenology of rare processes such as tt+X and tj+X.  I will also present some recent progresses on the inclusion of EW corrections from top-quark operators to Higgs measurements, where sizable corrections are found and seem to indicate that a more global view is needed for future runs at the LHC.
