Tri-hypercharge: a separate gauged weak hypercharge for each fermion family as the origin of flavour
Mario Fernández Navarro, Stephen F. King
We propose a tri-hypercharge (TH) embedding of the Standard Model (SM) in which a separate gauged weak hypercharge is associated with each fermion family. In this way, every quark…

Modular and Symmetries and Their Fixed Points: New Predictive Examples of Lepton Mixing
Gui-Jun Ding, Stephen F. King, Xiang-Gan Liu +1
In the modular symmetry approach to neutrino models, the flavour symmetry emerges as a finite subgroup of the modular symmetry, broken by the vacuum expectation value (VEV)…
