Non-holomorphic modular symmetry for leptons and leptogenesis
Cai-Chang Li, Jun-Nan Lu, Xiang-Yan Gao +2
We perform a comprehensive and systematic investigation of lepton models based on the non-holomorphic modular symmetry, by using level 4 polyharmonic Maaà forms s…
Two-zero textures of the Majorana neutrino mass matrix from gauging of non-invertible symmetry
Bu-Yao Qu, Zheng Jiang, Gui-Jun Ding
Texture-zero ansatze offer an economical description of neutrino masses, with current data allowing only seven inequivalent two-zero Majorana textures in the charged-lepton mass ba…
New modular fixed point models and their phenomenological implications for JUNO, T2HK and DUNE
Er-Hao Shang, Jun-Nan Lu, Gui-Jun Ding +1
We perform a general analysis of minimal modular fixed point models based on two right-handed neutrinos (2RHNs) and three modular fixed points, and find that the only viable possib…
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…
