Seminar: "Non-Abelian Discrete Symmetries for Flavour"

Wednesday, July 12, 2017 - 14:00 to 15:00

I will motivate the use of non-Abelian discrete symmetries (NADS) as tools to understand the Flavour Problem, i.e. the unexplained structure of fermionic mass and mixing in the Standard Model.  NADS are well-motivated both phenomenologically and in UV-complete theories, and, for many years, have been popular candidates to organize the flavour sector, including neutrino mixing.  I will review the intimate connection between the generators of non-Abelian finite groups and experimental mixing matrices before discussing the implementation of NADS in concrete physics models.  Finally, I will discuss ongoing efforts with my collaborators to write down an economical model of both quarks and leptons consistent with all available data.
