Description
This talk will discuss an effective field theory interpretation of simplified template cross section (STXS) stage 1.1 measurements at CMS. The Higgs Effective Lagrangian (HEL) is used to parameterise our lack of knowledge of the electroweak symmetry breaking sector by extending the Standard Model Lagrangian to higher orders in momentum expansion.
The status of STXS stage 1.1 measurements at CMS will be summarized. Following this, the derivation of scaling equations, which model the dependence of each STXS bin on the HEL parameters, will be described. These equations are then used to extract constraints on such parameters, by fitting STXS stage 1.1 measurements from a combination of Higgs boson decay channels.
