Abstract:
Despite its remarkable success, the Standard Model is not a complete
theory of particle physics. Empirical facts such as neutrino masses,
dark matter, and the observed matter-antimatter asymmetry clearly point
to physics beyond the SM. This talk will begin with an accessible
overview of the SM's accidental symmetries, which provide intriguing
clues about possible extensions. Using these symmetries as a guide, I
will introduce a simple high-energy model that ensures proton stability
while addressing key observational shortcomings of the SM. In the second
part of the talk, I will take a different direction and present BSM
scenarios that naturally motivate rare, high-multiplicity muon
decays — potential signatures that could interest MEG-II and Mu3e.
