Description
In this talk we will discuss how to perform precision calculations in the SMEFT framework, in order to parametrise small deviations from the SM predictions. We will discuss how to implement the complex mass scheme in an EFT calculation and how to go beyond leading order.  For this, we will focus on the H to 4 lepton channel. Further we will discuss how to extract numerical predictions for other electroweak processes, including backgrounds to the former,  in order to look for new physics within the LHC run-2 and upcoming runs.
