Abstract

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