A Radiative Neutrino Model with Triplet Fields
Takaaki Nomura, Hiroshi Okada, Yuta Orikasa
We propose a loop induced neutrino mass model, in which we introduce several exotic fermions and bosons with multiplet, and discuss various phenomenologies such as lepton…
A Three-loop Neutrino Mass Model with a Colored Triplet Scalar
Kingman Cheung, Takaaki Nomura, Hiroshi Okada
We study a variation of the Krauss-Nasri-Trodden (KNT) model with a colored triplet scalar field and a colored singlet scalar field, in which we discuss the anomaly coming from $b\…
A testable radiative neutrino mass model without additional symmetries and Explanation for the anomaly
Kingman Cheung, Takaaki Nomura, Hiroshi Okada
We propose a one-loop radiative Majorana-type neutrino-mass matrix without any kind of additional symmetries by introducing two leptoquark-like bosons only. In this scenario, we sh…
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…
Accommodation of the Dirac Phase in the Krauss-Nasri-Trodden Model
Kingman Cheung, Hiroyuki Ishida, Hiroshi Okada
We investigate one of the radiative models, Kraus-Nasri-Trodden model, with the maximal value of Dirac CP violating phase, is -π/2 (or equivalently 3π/2), which is preferred in…
Two-loop Induced Majorana Neutrino Mass in a Radiatively Induced Quark and Lepton Mass Model
Takaaki Nomura, Hiroshi Okada
A two-loop induced radiative neutrino model is proposed as an extension of our previous work in which the first and second generation standard model fermion masses are generated at…
