Solving the puzzle of particle flavour using the CMS experiment

One of the key conundrums in particle physics is the three-generation structure of the fermions and its vastly different mass spectrums. A currently unknown physics interaction at the beginning of the Universe, i.e. at a high energy scale, which acted differently depending on the fermion flavor, could have shaped the “flavor structure” we see today. The discovery of such an interaction is the ultimate goal of my research and is currently one of the top priorities in particle physics, given recent hints of Lepton Flavor Universality (LFU) violations reported by muon g-2 and B-physics experiments. In this colloquium, I will review my past/on-going/future research projects to tackle this conundrum uniquely at the CMS experiment. I have been using and will use the heavitest flavour of lepton, the tau, as a primary tool. I will also share my future prospects towards the next phase of LHC operation; particular focus is the development of a new scheme to select taus right at the first stage of the real-time selection of events. At the end of the colloquium, I will briefly share my vision towards future collider experiments.
