Search for new physics in top quark production with additional leptons in the context of effective field theory using 138fb$^{-1}$ of proton-proton collisions at $\sqrt{s}$ = 13 TeV. /CMS Collaboration
A search for new physics in top quark production with additional final-state leptons is performed with 138$\;\mathrm{fb^{-1}}$ of proton-proton collisions at $\sqrt{s}$ = 13$\;\mathrm{TeV}$ at the LHC, collected by the CMS detector during 2016, 2017, and 2018. Using the framework of effective field theory (EFT), potential new physics effects are parametrized in terms of 26 dimension-six EFT operators. EFT effects are incorporated into the event weights of the simulated samples, allowing detector-level predictions that account for correlations and interference effects among EFT operators and between EFT operators and standard model processes. The data are divided into several categories based on lepton multiplicity, total lepton charge, jet multiplicities, and $\mathrm{b}$ tagged jet multiplicities. Kinematic variables corresponding to the transverse momentum ($p_{\mathrm{T}}$) of the leading pair of leptons and jets as well as the $p_{\mathrm{T}}$ of on-shell $\mathrm{Z}$ bosons are used to extract the $95\%$ confidence intervals of the 26 dimension-six EFT operators. No significant deviation with respect to the standard model prediction was found..
