8. Flavor Physics and CP from Non-Invertible Selection Rules

In this talk, I will discuss the application of non-invertible selection rules to flavor physics and CP, in which matter fields are labeled by conjugacy classes of a finite group rather than its irreducible representations. We show that this framework leads to novel texture structures in the Yukawa couplings of quarks and leptons that cannot be realized by conventional group-theoretic...
