CMS measurements of EFT parameters with top quarks

Measurements carried out or reinterpreted within the framework of effective field theory (EFT) will constitute a key component of the LHC legacy in the quest towards physics beyond the standard model. Numerous EFT measurements were already published by the CMS Collaboration. In the top quark sector, four distinct approaches to EFT have been identified, each successfully applied in several analyses. We review the pros and cons of each approach, while illustrating them with recent analyses in which they were adopted.
