Combined effective field theory interpretation of Higgs boson, electroweak vector boson, top quark, and multi-jet measurements

Constraints on Wilson coefficients (WCs) corresponding to dimension-six operators of the standard model effective field theory (SMEFT) are determined from a simultaneous fit to seven sets of CMS measurements probing Higgs boson, electroweak vector boson, top quark, and multijet production. Masurements of electroweak precision observables are also included and provide complementary constraints to those from CMS experiment. The CMS measurements, using LHC proton-proton collision data at $\sqrt{s}$ = 13 TeV, corresponding to integrated luminosities of 36.3 or 138 fb$^{-1}$, are chosen to provide sensitivity to a broad set of operators, for which consistent SMEFT predictions can be derived. These are primarily measurements of differential cross sections which are parameterized as functions of the WCs. In measurements targeting $\text{t}(\bar{\text{t}})\text{X}$ production, SMEFT effects are modelled at the detector level. Individual constraints on 64 WCs, and constraints on 43 linear combinations of WCs, are obtained.
