FCNC and EFT interpretations in top quark events in CMS

Abstract

Top quark production can probe physics beyond the standard model (SM) in different ways. The Effective Field Theory (EFT) framework allows searching for beyond the SM (BSM) effects in a model independent way. CMS experiment is pioneering EFT measurements that move towards using full potential of the data in the most global way possible. Searches for flavour-changing neutral currents (FCNC) and anomalous top quark interactions are also being pursued in CMS which are complementary to the EFT approach. This talk reviews the current limits on FCNC searches in the top sector, and EFT interpretations.
