Search for new physics in top quark production with additional leptons in proton-proton collisions at root s=13 TeV using effective field theory
(Springer, 2021)
Events containing one or more top quarks produced with additional prompt leptons are used to search for new physics within the framework of an effective field theory (EFT). The data correspond to an integrated luminosity ...
