Neutrino Mass and Mixing Models with Eclectic Flavor Symmetry

Gui-Jun Ding, Stephen F. King, Cai-Chang Li +2

The Kähler potentials of modular symmetry models receive unsuppressed contributions which may be controlled by a flavor symmetry, where the combination of the two symmetry types is…

Modular symmetry at level 6 and a new route towards finite modular groups

Cai-Chang Li, Xiang-Gan Liu, Gui-Jun Ding

We propose to construct the finite modular groups from the quotient of two principal congruence subgroups as , and the modular group is extended to…

Modular Invariant Models of Leptons at Level 7

Gui-Jun Ding, Stephen F. King, Cai-Chang Li +1

We consider for the first time level 7 modular invariant flavour models where the lepton mixing originates from the breaking of modular symmetry and couplings responsible for lepto…

A New Littlest Seesaw Model

Ping-Tao Chen, Gui-Jun Ding, Stephen F. King +1

We propose and discuss a new Littlest Seesaw model, realised in the tri-direct CP approach, in which the couplings of the two right-handed neutrinos to the lepton doublets are prop…
