EFT Results in the Top Quark Sector in CMS

The CMS programme of indirect searches in the top-quark sector interprets precision measurements in the Standard Model Effective Field Theory (SMEFT) framework. This proceedings summarises recent CMS results highlighted in the TOP2025 talk: a searchfor CP violation in t¯tZ and tZq production using CP-odd observables constructed with physics-informed machine learning, ameasurement that disentangles the flavour structure of electroweak SMEFT couplings in multilepton final states, and a Run 2combination of complementary top+X measurements. We close with a brief outlook on the expected sensitivity gains at thehigh-luminosity LHC.
