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 Zeros
Xiang-Gan Liu, Michael Ratz
Modular symmetries are known to be powerful and have various remarkable properties. We point out that the structure of vector-valued modular forms (VVMFs) space leads to the absenc…
Demystifying stringy miracles with eclectic flavor symmetries
V. Knapp-Perez, Xiang-Gan Liu, Hans Peter Nilles +1
Effective field theories arising from string compactifications are subject to constraints originating from the duality transformations of string theory. Interpreting these so-calle…
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…
