Pyroelectric detection of spontaneous polarization in magnetite thin films
R. Takahashi, H. Misumi, M. Lippmaa
We have investigated the spontaneous polarization in FeO thin films by using dynamic and static pyroelectric measurements. The magnetic and dielectric behavior of FeO$_…
Stability of Leptonic Self-complementarity
Naoyuki Haba, Kunio Kaneta, Ryo Takahashi
We investigate a stability of leptonic self-complementarity such that sum of three mixing angles in lepton sector is 90 degrees. Renormalization group equations in a context of min…
Enhancement of Higgs to diphoton decay width in non-perturbative Higgs model
Naoyuki Haba, Kunio Kaneta, Yukihiro Mimura +1
We investigate a possibility if a loop diagram via Higgsino can enhance the Higgs to diphoton decay width in supersymmetric models with an extension of Higgs sector. A model with a…
Grand Unification of Flavor Mixings
Naoyuki Haba, Ryo Takahashi
An origin of flavor mixings in quark and lepton sectors is still a mystery, and a structure of the flavor mixings in lepton sector seems completely different from that of quark sec…
Magnetic dipole moment and keV neutrino dark matter
Chao-Qiang Geng, Ryo Takahashi
We study magnetic dipole moments of right-handed neutrinos in a keV neutrino dark matter model. This model is a simple extension of the standard model with only right-handed neutri…
