Fermion mass relations in one-parameter modular models
Salvador Centelles Chuliá, Xueqi Li, Xiang-Gan Liu +2
Modular flavour symmetries provide a possible organizing principle for the Standard Model Yukawa sector, by replacing generic couplings with a potentially small number of modular f…
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…
Flavor Symmetries and Winding Modes
Xueqi Li, Xiang-Gan Liu, Hans Peter Nilles +2
Modular flavor symmetries have been proposed as a new way to address the flavor problem. It is known that they can emerge from string compactifications. We discuss this connection…
Multiple realizations of modular flavor symmetries and their phenomenology
Carlos Arriaga-Osante, Mu-Chun Chen, Ramon Diaz-Castro +4
We point out that specifying the finite modular group does not uniquely fix a modular flavor symmetry. We illustrate this using the finite modular group . Otherwise equivalent…
