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…

Modular invariant holomorphic observables
Mu-Chun Chen, Xiang-Gan Liu, Xue-Qi Li +2
In modular invariant models of flavor, observables must be modular invariant. The observables discussed so far in the literature are functions of the modulus and its conjugate,…

Quark-lepton mass relations from modular flavor symmetry
Mu-Chun Chen, Stephen F. King, Omar Medina +1
The so-called Golden Mass Relation provides a testable correlation between charged-lepton and down-type quark masses, that arises in certain flavor models that do not rely on Grand…
