Description
A generalized extension of the standard model of particle physics (SM), known as standard model effective field theory (SMEFT), consists of all the possible operators of dimensions greater than four, satisfying the symmetries of the SM Lagrangian. SMEFT operators, which systematically parameterize the impact of physics beyond the SM in a model-independent way, modify the production and decay kinematics of the Higgs boson compared with those predicted by the SM. I will discuss the techniques used by the CMS experiment to constrain the SMEFT operators in the Higgs sector and report the corresponding results.
