Abstract: The discovery of the Higgs boson at the LHC in 2012 was the main
achievement of particle physics in recent years. Since then,
particle physicists have been trying to understand in detail the
properties of the new state: its mass, quantum numbers and how it
interacts with the other known particles. An important tool in
this program is the Standard Model Effective Field
Theory (SMEFT). I will discuss the discovery of the Higgs boson,
motivate the SMEFT and discuss its role in the search for Beyond
Standard Model physics. Finally, I will present the construction
of new angular observables in decays of the Higgs to four leptons
in the context of the SMEFT.
