Radiative lepton model in a non-invertible fusion rule
Takaaki Nomura, Hiroshi Okada, Yoshihiro Shigekami
We propose a radiatively induced lepton mass model introducing a gauging fusion rule. In our framework, the charged-lepton mass matrix is generated at one-loop level vi…
Zee models with a non-invertible symmetry
Huiji Jin, Takaaki Nomura, Hiroshi Okada
We investigate Zee models by incorporating a non-invertible symmetry. The models are systematically classified based on their symmetry assignments, which dictate structures f…
A theoretical account of tiny multi-Higgs vacuum expectation values from non-invertible symmetry
Takaaki Nomura, Hiroshi Okada
We propose a novel mechanism to explain the naturally small vacuum expectation values (VEVs) of exotic multi-Higgs fields by employing non-invertible symmetries. Specifically, we i…
Predictions of Modular Symmetry Fixed Points on Neutrino Masses, Mixing, and Leptogenesis
Priya, B. C. Chauhan, Deepak Kumar +1
In recently proposed framework of non-holomorphic modular symmetry introduces the concept of negative and zero modular weight of Yukawa couplings. These Yukawa couplings are functi…
Lepton seesaw model in a modular symmetry
Takaaki Nomura, Hiroshi Okada
We propose a lepton seesaw model to get the same mass-origin of charged-leptons and neutrinos introducing a modular symmetry. In this scenario, the mass matrix of charged-lep…
A Minimal Realization of Radiative Dirac Neutrino Masses via a Non-Invertible Fusion Rule
Takaaki Nomura, Hiroshi Okada, Yoshihiro Shigekami
We propose a minimal one-loop radiative framework for Dirac neutrino mass matrix. As a consequence, the Yukawa hierarchies among the SM fermions are alleviated, and radiative type-…
