Probing the flavour structure of dimension-6 EFT operators in multilepton final states /CMS Collaboration
An analysis of the flavour structure of dimension-6 effective field theory (EFT) operators in multilepton final states is presented, focusing on the interactions involving Z bosons. The flavour structure of these operators is disentangled by simultaneously probing the interactions with different quark generations in final states with at least three leptons, targetting the associated production of a top quark pair and a Z boson (t¯tZ) as well as diboson processes (WZ and ZZ).
