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 Maaß 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 Maaß 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 Maaß forms. The integer weight polyharmonic Maaß 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…
