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…

Two-loop rainbow neutrino masses in a non-invertible symmetry

Hiroshi Okada, Yoshihiro Shigekami

We propose two-loop rainbow type of the neutrino mass model via gauging of non-invertible symmetry in which we introduce three families of isospin doublet vector-li…

A novel realization of linear seesaw model in a non-invertible selection rule with the assistance of symmetry

Hiroshi Okada, Yutaro Shoji

We propose a novel realization of linear seesaw model in a non-invertible selection rule with the assistance of symmetry. In our framework, Dirac mass matrices are ge…

A radiative seesaw model in a non-invertible selection rule with the assistance of a non-holomorphic modular symmetry

Shilpa Jangid, Hiroshi Okada

We propose a two-loop neutrino mass model where fermionic and bosonic dark matter (DM) candidates are simultaneously connected to the neutrinos. But the fermionic DM candidate is f…

A natural realization of inverse seesaw model in a non-invertible selection rule

Shilpa Jangid, Hiroshi Okada

We propose natural hierarchies among neutral fermions in a framework of inverse seesaw, imposing a Tambara-Yamagami fusion rule which is applied to our phenomenology. Under t…
