Hierarchically Acting Sterile Neutrinos
Chian-Shu Chen, Ryo Takahashi
We propose that a hierarchical spectrum of sterile neutrinos (eV, keV, GeV) is considered to as the explanations for MiniBooNE and LSND oscillation anomalies, dark mat…
A4 Flavor Models in Split Seesaw Mechanism
Adisorn Adulpravitchai, Ryo Takahashi
A seesaw mechanism in an extra-dimension, known as the split seesaw mechanism, provides a natural way to realize a splitting mass spectrum of right-handed neutrinos. It leads to on…
Predictions via large theta13 from cascades
Naoyuki Haba, Ryo Takahashi
We investigate a relation among neutrino observables, three mixing angles and two mass squared differences, from a cascade texture of neutrino mass matrix. We show an allowed regio…
Dirichlet Higgs as radion stabilizer in warped compactification
Naoyuki Haba, Kin-ya Oda, Ryo Takahashi
We study implications of generalized non-zero Dirichlet boundary condition along with the ordinary Neumann one on a bulk scalar in the Randall-Sundrum warped compactification. Firs…
