Abstract: The Run II dataset, collected by the CMS from 2016 to 2018, provided a unique opportunity to precisely study SM processes and obtain clues to New Physics. During my PhD, I took advantage of this opportunity to perform two complementary searches for New Physics signals, employing third-generation final-state fermions to increase the sensitivity of the investigations. In the first study, I searched for a new W' boson in the context of the Sequential Standard Model with a focus on its decay to a tb quark pair, considering many different scenarios and extending the mass range of previous studies. In the second, I established a measurement of the vector boson scattering of a same-charge W pair, considering for the first time a tau lepton decaying to hadrons in the final state, together with a search for anomalous W couplings with bosons and fermions. I used the SM-EFT approach to model and interpret these possible low-energy anomalies induced by New Physics phenomena, with the ultimate goal of providing precise indications of the most promising directions for discoveries. Thanks to these studies, I also gained expertise in Monte Carlo simulations for hard scattering processes and had the opportunity to contribute to the Tracker DQM
