A search for new physics in top quark production with additional final-state leptons is performed 138 $\mathrm{fb}^{-1}$ of proton-proton collision data at $\sqrt{s}$ = 13 TeV. We use the framework effective field theory to parametrize potential effects terms 26 dimension-six EFT operators. The are divided into several categories based on lepton multiplicity, total charge, jet multiplicities, and b-tagged multiplicities. Kinematic variables used extract limits simultaneously associated set Wilson coefficients.
