1. A model with flavor-dependent gauged symmetrySupported by National Center for Theoretical Sciences and MoST (MoST-104-2112-M-007-003-MY3 and MoST-107-2119-M-007-013-MY3) / Mu, Linping ; Okada, Hiroshi ; Geng, Chao-Qiang
We propose a new model with flavor-dependent gauged symmetry in addition to the flavor-blind symmetry in the Standard Model. [...]

6. A radiative seesaw model with higher order terms under an alternative U (1) B − L / Nomura, Takaaki ; Okada, Hiroshi
We propose a model based on an alternative U(1)B−L gauge symmetry with 5 dimensional operators in the Lagrangian, and we construct the neutrino masses at one-loop level, and discuss lepton flavor violations, dark matter, and the effective number of neutrino species due to two massless particles in our model.

7. Hidden U(1) gauge symmetry realizing a neutrinophilic two-Higgs-doublet model with dark matter / Nomura, Takaaki ; Okada, Hiroshi
We propose a neutrinophilic two-Higgs-doublet model with hidden local U(1) symmetry, where active neutrinos are Dirac type, and a fermionic dark matter (DM) candidate is naturally induced as a result of remnant symmetry even after the spontaneous symmetry breaking. [...]

8. Generalized one-loop neutrino mass model with charged particles / Cheung, Kingman ; Okada, Hiroshi
We propose a radiative neutrino-mass model by introducing 3 generations of fermion pairs E(N+1)/2E+(N+1)/2 and a couple of multicharged bosonic doublet fields ΦN/2,ΦN/2+1, where N=1, 3, 5, 7, 9. [...]
