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. Constraints on six Wilson coefficients that modify interactions between four third-generation quarks or between top quarks and the Higgs boson in the standard model effective field theory framework are derived. The data are further used to exclude narrow topphilic heavy resonances in the mass ranges between 400 GeV and 1.6 TeV depending on their spin and color states. Finally, the top quark Yukawa coupling is extracted, considering both $CP$-even and $CP$-odd contributions.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.161622.v1/t1","@type":"Dataset","description":"Negative log-likelihood difference from the best fit value for the one-dimensional scan of the WC $c_{\\mathrm{tt}}$, where the other WCs...","name":"1D EFT scan ctt (others zero)"},{"@id":"https://doi.org/10.17182/hepdata.161622.v1/t2","@type":"Dataset","description":"Negative log-likelihood difference from the best fit value for the one-dimensional scan of the WC $c_{\\mathrm{tt}}$, where the other WCs...","name":"1D EFT scan ctt (others profiled)"},{"@id":"https://doi.org/10.17182/hepdata.161622.v1/t3","@type":"Dataset","description":"Negative log-likelihood difference from the best fit value for the one-dimensional scan of the WC $c_{\\mathrm{QQ}}^{(1)}$, where the other WCs...","name":"1D EFT scan cQQ1 (others zero)"},{"@id":"https://doi.org/10.17182/hepdata.161622.v1/t4","@type":"Dataset","description":"Negative log-likelihood difference from the best fit value for the one-dimensional scan of the WC $c_{\\mathrm{QQ}}^{(1)}$, where the other WCs...","name":"1D EFT scan cQQ1 (others profiled)"},{"@id":"https://doi.org/10.17182/hepdata.161622.v1/t5","@type":"Dataset","description":"Negative log-likelihood difference from the best fit value for the one-dimensional scan of the WC $c_{\\mathrm{Qt}}^{(1)}$, where the other WCs...","name":"1D EFT scan cQt1 (others zero)"},{"@id":"https://doi.org/10.17182/hepdata.161622.v1/t6","@type":"Dataset","description":"Negative log-likelihood difference from the best fit value for the one-dimensional scan of the WC $c_{\\mathrm{Qt}}^{(1)}$, where the other WCs...","name":"1D EFT scan cQt1 (others profiled)"},{"@id":"https://doi.org/10.17182/hepdata.161622.v1/t7","@type":"Dataset","description":"Negative log-likelihood difference from the best fit value for the one-dimensional scan of the WC $c_{\\mathrm{Qt}}^{(8)}$, where the other WCs...","name":"1D EFT scan cQt8 (others zero)"},{"@id":"https://doi.org/10.17182/hepdata.161622.v1/t8","@type":"Dataset","description":"Negative log-likelihood difference from the best fit value for the one-dimensional scan of the WC $c_{\\mathrm{Qt}}^{(8)}$, where the other WCs...","name":"1D EFT scan cQt8 (others profiled)"},{"@id":"https://doi.org/10.17182/hepdata.161622.v1/t9","@type":"Dataset","description":"Negative log-likelihood difference from the best fit value for the one-dimensional scan of the WC $c_{\\mathrm{tH}}^{\\mathrm{Re}}$, where the other WCs...","name":"1D EFT scan ctHRe (others zero)"},{"@id":"https://doi.org/10.17182/hepdata.161622.v1/t10","@type":"Dataset","description":"Negative log-likelihood difference from the best fit value for the one-dimensional scan of the WC $c_{\\mathrm{tH}}^{\\mathrm{Re}}$, where the other WCs...","name":"1D EFT scan ctHRe (others profiled)"},{"@id":"https://doi.org/10.17182/hepdata.161622.v1/t11","@type":"Dataset","description":"Negative log-likelihood difference from the best fit value for the one-dimensional scan of the WC $c_{\\mathrm{tH}}^{\\mathrm{Im}}$, where the other WCs...","name":"1D EFT scan ctHIm (others zero)"},{"@id":"https://doi.org/10.17182/hepdata.161622.v1/t12","@type":"Dataset","description":"Negative log-likelihood difference from the best fit value for the one-dimensional scan of the WC $c_{\\mathrm{tH}}^{\\mathrm{Im}}$, where the other WCs...","name":"1D EFT scan ctHIm (others profiled)"},{"@id":"https://doi.org/10.17182/hepdata.161622.v1/t13","@type":"Dataset","description":"Constraints on the individual WCs, obtained by either fixing the other WCs to zero or profiling them.
