Abstract

In absence of any distinct evidence of new physics phenomena at the LHC, an increasing number of experimental studies aim at probing anomalous effects with an effective field theory (EFT) that represents a comprehensive approach for interpretation of various experimental results. The processes with the production of top quarks are sensitive to several classes of EFT operators including the flavour-changing neutral currents (FCNC). The summary of the latest CMS results based on the recent studies of the standard model processes and searches for new physics effects involving top quarks are presented.
