Top quark as a probe for new physics

The top quark, since its discovery in 1995, has been a focal point of investigations in high-energy particle physics. Its large mass, close to the electroweak scale, makes it a sensitive probe for potential new physics beyond the Standard Model (BSM). In this talk I will present an overview of experimental searches for new physics where top quarks appear in the final state, with a focus on recent results from the CMS Experiment at CERN LHC. I will also discuss experimental techniques used to identify top quarks and an outlook for the future of this kind of searches.
