modular inflation
Si-Yi Jiang, Wenbin Zhao, Gui-Jun Ding
We investigate inflation models governed by the Siegel modular group . The group extends the framework from one modulus to t…
Non-holomorphic modular flavor symmetry and odd weight polyharmonic Maaà form
Bu-Yao Qu, Jun-Nan Lu, Gui-Jun Ding
We extend the framework of non-holomorphic modular flavor symmetry to include the odd weight polyharmonic Maaà forms. The integer weight polyharmonic Maaà forms of level can…
Discrete flavour and CP symmetries in light of JUNO and neutrino global fit
Gui-Jun Ding, Cai-Chang Li, Jun-Nan Lu +1
Working within the reference three-neutrino mixing framework, we confront the lepton mixing predictions derived using non-Abelian discrete flavour and CP symmetries with the first…
Modular invariant inflation and reheating
Gui-Jun Ding, Si-Yi Jiang, Yong Xu +1
We use modular symmetry as an organizing principle that attempts to simultaneously address the lepton flavor puzzle, inflation, and post-inflationary reheating. We demonstrate this…
Texture-zeros in minimal seesaw from non-invertible symmetry fusion rules
Zheng Jiang, Bu-Yao Qu, Gui-Jun Ding
The gauging of symmetry can enforce certain elements of the fermion Yukawa couplings to vanish. We have performed a systematical study of texture zero patterns of lepto…
Lepton models from non-holomorphic modular flavor symmetry
Cai-Chang Li, Gui-Jun Ding
In the framework of non-holomorphic modular invariance approach, we have systematically constructed all minimal lepton models based on the non-holomorphic modular…
