Summary

We construct mass terms for the Standard Model fermions of the first generation. This includes the neutrino, where we invoke either a dimension-5 term or we add a right-handed neutrino field. We reconsider the CP symmetry, the fate of baryon and lepton numbers, and the quantization of the electric charge. The question of the mass hierarchy takes us to the seesaw mass-by-mixing mechanism. As a peculiarity, we finally revisit such properties in the scenario without colors (Nc=1), which allows leptons and baryons to mix.
