| Abstract A search for new physics in top quark production with additional final-state leptons is performed using data collected by the CMS experiment in proton-proton collisions at = 13 TeV at the LHC during 2016–2018. The data set corresponds to an integrated luminosity of 138 fb −1. Using the framework of effective field theory (EFT), potential new physics effects are parametrized in terms of 26 dimension-six EFT operators. The impacts of EFT operators are incorporated through the event-level reweighting of Monte Carlo simulations, which allows for detector-level predictions. The events are divided into several categories based on lepton multiplicity, total lepton charge, jet multiplicity, and b-tagged jet multiplicity. Kinematic variables corresponding to the transverse momentum (p T) of the leading pair of leptons and/or jets as well as the p T of on-shell Z bosons are used to extract the 95% confidence intervals … |
