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…
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-…
Radiative Dirac Neutrino Masses from Modular Symmetry in an Axion Model
Sin Kyu Kang, Ranjeet Kumar, Hiroshi Okada
We present a unified axion model framework that simultaneously addresses the origin of neutrino masses, leptonic flavor structure, the strong CP problem, and dark matter. The model…
A radiative lepton model in a non-invertible fusion rule
Jingqian Chen, Chao-Qiang Geng, Hiroshi Okada +1
We propose a new mechanism in which electron and muon masses are induced at one-loop level after dynamically violating the symmetry of the Ising fusion rule. In the neutrino sector…
Radiative lepton seesaw model in a non-invertible fusion rule and gauged symmetry
Takaaki Nomura, Hiroshi Okada
We propose a radiative lepton seesaw model with the Tambara-Yamagami fusion rule and gauged symmetry. The heavier right-handed neutral fermions () simult…
Neutrino mass model at a three-loop level from a non-holomorphic modular symmetry
Takaaki Nomura, Hiroshi Okada
We study a three-loop induced neutrino mass scenario from a non-holomorphic modular flavor symmetry and reach the minimum scenario leading predictions of the lepton masses, m…
A radiative neutrino mass model with leptoquarks under non-holomorphic modular symmetry
Takaaki Nomura, Hiroshi Okada, Xing-Yu Wang
We investigate a radiative seesaw model with two leptoquarks under non-holomorphic modular symmetry. The leptons and quarks belong to non-trivial representations of the modul…
Radiative neutrino mass models from non-invertible selection rules
Tatsuo Kobayashi, Hiroshi Okada, Hajime Otsuka
We apply non-invertible selection rules coming from a fusion algebra to radiative neutrino mass models where fields are labeled by the elements in the algebra. Since non-invertible…
A new type of lepton seesaw model in a modular symmetry
Takaaki Nomura, Hiroshi Okada
We propose a new type of lepton seesaw model introducing a modular flavor symmetry in which isospin doublet vector fermions play an important role in constructing seesaw mech…
Zee-Babu model in a non-holomorphic modular symmetry and modular stabilization
Tatsuo Kobayashi, Hiroshi Okada, Yuta Orikasa
We study a Zee-Babu neutrino model in a non-holomorphic modular symmetry, and we construct a model so that there are minimum free parameters (two complex parameters). We find…
A radiative seesaw in a non-holomorphic modular flavor symmetry
Hiroshi Okada, Yuta Orikasa
We study a non-holomorphic modular flavor symmetry in which we analyze neutrino sector, dark matter, and lepton flavor violations. The active neutrino mass is generated via o…
