Since the discovery of the muon in the cosmic ray radiation, the study of the properties and decays of this particle contributed to build and test the Standard Model (SM) of particle physics. Still now, being the lightest unstable particle in the SM, the muon with its decays provides a unique environment to search for New Physics (NP) phenomena. Additionally, in recent years, we have seen an increasing interest on a multi-TeV muon collider option for combining NP searches at the energy and precision frontier.
