Scotogenic neutrino mass with large multiplet fields
Nilanjana Kumar, Takaaki Nomura, Hiroshi Okada
We construct a scotogenic neutrino mass model introducing large multiplet fields without adding an extra symmetry. We have introduced extra scalar fields such as a septet…
An Inverse Seesaw model with -modular symmetry
Takaaki Nomura, Hiroshi Okada, Sudhanwa Patra
We discuss an inverse seesaw model based on right-handed fermion specific gauge symmetry and -modular symmetry. These symmetries forbid unnecessary terms and restrict s…
Neutrino mass model with a modular symmetry
Hiroshi Okada, Yuta Orikasa
We propose a predictive lepton model under a modular symmetry, where the neutrino mass matrix arises from a radiative seesaw at one-loop level. The tree-level mass matrix is…
A modular symmetric scotogenic model
Takaaki Nomura, Hiroshi Okada, Oleg Popov
We propose a minimal extention of the Standard Model where neutrino masses are generated radiatively at one-loop level via Scotogenic scanario. The model is augmented with mo…
A radiative seesaw model in modular symmetry
Hiroshi Okada, Yuta Orikasa
We study one-loop induced radiative seesaw model applying a modular flavor symmetry, in which the neutrino mass matrix is achieved by two different Yukawa couplings one of wh…
Modular symmetric radiative seesaw model
Hiroshi Okada, Yuta Orikasa
We propose a one-loop induced radiative seesaw model applying a modular flavor symmetry, which is known as the minimal non-Abelian discrete group. In this scenario, dark matt…
