A Three-loop Neutrino Model with Leptoquark Triplet Scalars
Kingman Cheung, Takaaki Nomura, Hiroshi Okada
We propose a three-loop neutrino mass model with a few leptoquark scalars in -triplet form, through which we can explain the anomaly of , a sizable…
A Colored KNT Neutrino Model
Takaaki Nomura, Hiroshi Okada, Nobuchika Okada
We propose a radiative seesaw model at the three-loop level, in which quarks, leptons, leptoquark bosons, and a Majorana fermion of dark matter candidate are involved in the neutri…
Quark mixing from Delta(6N^2) family symmetry
Hajime Ishimori, Stephen F. King, Hiroshi Okada +1
We consider a direct approach to quark mixing based on the discrete family symmetry Delta (6N^2) in which the Cabibbo angle is determined by a residual Z_2 times Z_2 subgroup to be…
3.55 keV X-ray Line Signal from Excited Dark Matter in Radiative Neutrino Model
Hiroshi Okada, Takashi Toma
We study an exciting dark matter scenario in a radiative neutrino model to explain the X-ray line signal at keV recently reported by XMN-Newton X-ray observatory using data…
