Casimir energy between two parallel plates and projective representation of Poincaré group
Takamaru Akita, Mamoru Matsunaga
The Casimir effect is a physical manifestation of zero point energy of quantum vacuum. In a relativistic quantum field theory, Poincaré symmetry of the theory seems, at first sight…
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…
Quantization of hypercharge in gauge groups locally isomorphic but globally nonisomorphic to SU(3)_c X SU(2)_L X U(1)_Y
Takaaki Hashimoto, Mamoru Matsunaga, Kenta Yamamoto
In the Standard Model the hypercharges of quarks and leptons are not determined by the gauge group itself. In a recent paper [C. Hattori et al. Phys. Rev. D83, 015009 (2011)] it is…
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…
