CMS performs a combined SMEFT fit to multiple LHC measurements and precision data, yielding individual constraints on 64 Wilson coefficients and 43 linear combinations.
CMS derives limits on six SMEFT Wilson coefficients, excludes topphilic resonances between 400-1600 GeV, and extracts the top Yukawa coupling from multi-lepton top events in 138 fb^{-1} of 13 TeV data.
