  Using data consisting of top quarks produced with additional final leptons
collected by the CMS detector at a center-of-mass energy of $\sqrt{s}=$13 TeV
from 2016 to 2018 (138 fb$^{-1}$), a search for beyond standard model (BSM)
physics is presented. The BSM physics is probed in the context of Effective
Field Theory (EFT) by parameterizing potential new physics effects in terms of
26 dimension-six EFT operators. The data are categorized based on lepton
multiplicity, total lepton charge, jet multiplicities, and b-tagged jet
multiplicities. To gain further sensitivity to potential new physics (NP)
effects, events in each jet category are binned using kinematic differential
distributions. A simultaneous fit to data is performed to put constraints on
the 26 operators. The results are consistent with the standard model
prediction.
