Anarchy and Hierarchy
Naoyuki Haba, Hitoshi Murayama
We advocate a new approach to study models of fermion masses and mixings, namely anarchy proposed in hep-ph/9911341. In this approach, we scan the O(1) coefficients randomly. We ar…
Spin Gap of S=1/2 Heisenberg Model on Distorted Diamond Chain
Kazuhiro Sano, Ken'ichi Takano
We study the spin gap of the S=1/2 Heisenberg model on the distorted diamond chain, which is recently proposed to represent magnetic properties of Cu_3 Cl_6 (H_2 O)_2 2H_8 C_4 SO_2…
The effects of Majorana phases in three-generation neutrinos
N. Haba, Y. Matsui, N. Okamura
Neutrino-oscillation solutions for the atmospheric neutrino anomaly and the solar neutrino deficit can determine the texture of the neutrino mass matrix according to three types of…
Are lepton flavor mixings in the democratic mass matrix stable against quantum corrections?
N. Haba, Y. Matsui, N. Okamura +1
We investigate whether the lepton flavor mixing angles in the so-called democratic type of mass matrix are stable against quantum corrections or not in the minimal supersymmetric s…
