Lepton mixing from the Modular Littlest Seesaw

Hai-Zhi Hao, Li-Na Yan, Xiang-Gan Liu +1

We perform the first comprehensive and model independent study of Modular Littlest Seesaw models based on the finite modular group . We construct the vector-valued modular f…

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…

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…

Flavor mixing and CP violation from the interplay of modular group and gCP

Bu-Yao Qu, Xiang-Gan Liu, Ping-Tao Chen +1

We have performed a systematical analysis of lepton and quark masses models based on modular symmetry with gCP symmetry. We have considered both cases that neutrinos…

CP Symmetry and Symplectic Modular Invariance

Gui-Jun Ding, Ferruccio Feruglio, Xiang-Gan Liu

We analyze CP symmetry in symplectic modular-invariant supersymmetric theories. We show that for genus the definition of CP is unique, while two independent possibilities…

Automorphic Forms and Fermion Masses

Gui-Jun Ding, Ferruccio Feruglio, Xiang-Gan Liu

We extend the framework of modular invariant supersymmetric theories to encompass invariance under more general discrete groups , that allow the presence of several moduli and m…

Half-integral weight modular forms and application to neutrino mass models

Xiang-Gan Liu, Chang-Yuan Yao, Bu-Yao Qu +1

We generalize the modular invariance approach to include the half-integral weight modular forms. Accordingly the modular group should be extended to its metaplectic covering group…

Modular Symmetry Models of Neutrinos and Charged Leptons

Gui-Jun Ding, Stephen F. King, Xiang-Gan Liu

We present a comprehensive analysis of neutrino mass and lepton mixing in theories with modular symmetry, where the only flavon field is the single modulus field , and all…

Neutrino Masses and Mixing from Double Covering of Finite Modular Groups

Xiang-Gan Liu, Gui-Jun Ding

We extend the even weight modular forms of modular invariant approach to general integral weight modular forms. We find that the modular forms of integral weights and level can…
