Can a minimal radiative seesaw explain the LZ 248 keV event?
Hiroshi Okada, Yoshihiro Shigekami, Jia-Jun Wu
We interpret the recently reported 248~keV nuclear recoil event in the LUX-ZEPLIN (LZ) experiment via inelastic dark matter scattering within the minimal Scotogenic model. A sub-Me…
Radiative double inverse seesaw and dark matter in an alternative gauged model
Hiroshi Okada, Labh Singh
We propose a concrete theoretical framework for the double inverse seesaw mechanism within an alternative gauged model, where the tiny neutrino masses emerge radiative…
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…
Dynamical CP Violation from Non-Invertible Selection Rules
Hiroshi Okada, Hajime Otsuka
We propose a novel mechanism in which leptonic CP-violating phases are generated dynamically through the radiative breaking of non-invertible selection rules. In this framework, tr…
Dirac one-loop seesaw in a non-invertible fusion rule
Hiroshi Okada, Labh Singh
We propose a radiative Dirac neutrino mass model stabilized by a non-invertible fusion rule originating from a gauging. The imposed symmetry forbids tree-level Yu…
Dynamical Determination of the Cut-off Scale in Loop-Induced Neutrino Mass Models with Non-Invertible Symmetry
Hiroshi Okada, Jia-Jun Wu
We propose our framework as an effective field theory valid below the cut-off scale , in which we explain the tiny scale of neutrino masses by integrating a non-invertible symme…
