报告摘要: 

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