Quark CP-Phase and Froggatt-Nielsen Mechanism
Chuichiro Hattori, Masahisa Matsuda, Mamoru Matsunaga +1
On the basis of the Froggatt-Nielsen mechanism, we study quark flavor mixings in the model. The characteristic structure of the CKM matrix is attributed to t…
Maki-Nakagawa-Sakata matrix and Froggatt-Nielsen mechanism
Chuichiro Hattori, Mamoru Matsunaga, Takeo Matsuoka
Flavor mixings together with fermion mass spectra are studied in detail in the model, in which state-mixings beyond the minimal supersymmetric standard model…
Semidirect product gauge group and quantization of hypercharge
Chuichiro Hattori, Mamoru Matsunaga, Takeo Matsuoka
In the Standard Model the hypercharges of quarks and leptons are not determined by the gauge group alone. We show that, if…
gauge symmetry and Tri-bimaximal mixing
Chuichiro Hattori, Mamoru Matsunaga, Takeo Matsuoka +1
We study an effective gauge theory whose gauge group is a semidirect product with and being a connected Lie group and a finite group, re…
Flavor Symmetry and Galois Group of Elliptic Curves
Chuichiro Hattori, Mamoru Matsunaga, Takeo Matsuoka +1
A new approach to the generation structure of fermions is proposed. We consider a brane configuration in which the brane intersection yields a two-torus in the extra space. It is a…
Galois Group of Elliptic Curves and Flavor Symmetry
Chuichiro Hattori, Mamoru Matsunaga, Takeo Matsuoka +1
Putting emphasis on the relation between rational conformal field theory (RCFT) and algebraic number theory, we consider a brane configuration in which the D-brane intersection is…
