Abstract: The Standard Model Effective Field Theory (SMEFT) is one of the most important methods of interpreting data from the LHC as well as other experiments. In this talk I will use the lack of discovery of physics beyond the Standard Model to motivate the use of Effective Field Theories (EFTs) for studying experimental data. I will give a brief introduction to EFTs and the SMEFT, discuss global fits to the free parameters of the SMEFT and their interpretation. Then I will discuss the relevance of higher order terms in the SMEFT expansion (inverse powers of the heavy mass scale of new physics) and how the Universal SMEFT allows us to make progress in constraining the contribution of higher order terms in the expansion.
