Strong and Quark Mass Hierarchies from Modular Invariance
Xiang-Gan Liu, Michael Ratz, Alexander Stewart
The strong problem and quark mass hierarchies can probe the same ultraviolet structure. We show this by extending modular strong- solutions to non-Abel…

INFLAVON: CMB as cosmic tracer of Flavor physics
Mu-Chun Chen, Anish Ghoshal, V. Knapp-Perez +3
We unify one of the most widely studied frameworks to explain the hierarchical structure of the flavor sector in the Standard Model, the Froggatt-Nielsen mechanism, with cosmic inf…

Modular Flavor Symmetries and Fermion Mass Hierarchies
Mu-Chun Chen, Xueqi Li, Xiang-Gan Liu +1
We investigate fermion mass hierarchies in models with modular flavor symmetries. Several key conclusions arise from the observation that the determinants of mass matrices transfor…
