| Abstract: An interpretation of a measurement of four and three top quark production in different scenarios of new physics beyond the standard model (SM) is reported. The analyzed proton-proton collision data were recorded at 13 TeV with the CMS detector at the CERN LHC in 2016-2018 and correspond to an integrated luminosity of 138 fb$ ^{-1} $. Events with two same-sign, three, or four leptons (electrons and/or muons) are selected. Using the SM effective field theory framework, constraints on six Wilson coefficients are derived that modify interactions between four third-generation quarks or between top quarks and the Higgs boson. Exclusion limits are derived on top-philic heavy resonances of different spin and color states, covering masses between 400 GeV and 1.6 TeV. The top quark Yukawa coupling is extracted, considering both $ CP $-even and $ CP $-odd contributions. | ||
