Description
Even though it is one of the most successful theories in all of physics, the Standard Model (SM) of particle physics cannot be a final theory. Some experimental results, ranging from the detection of B meson decays that should involve flavour changing neutral currents, to the detection of neutrino oscillations, seem to point to the existence of new physics beyond the SM. The introduction of very heavy vector-like quarks and the addition of right-handed neutrinos in the framework of Majorana neutrinos are two promising proposals that seem to be able to accommodate some the experimental results.
With these extensions in mind, in the electroweak sector, this work aims to find new symmetries or ansatzes that could constrain the form of the fermion mass matrices, reducing the free parameters of the theory while generating the observed experimental results. The study of the possible implications of these promising extensions on CP violation will be another focus of this work.
