Quark/lepton mass and mixing in S_3 invariant model and CP-violation of neutrino

Tadayuki Teshima, Yoshitaka Okumura

Weak bases of flavors (u, c), (d,s), (e, μ), (ν_e,ν_μ) are assumed as the S_3 doublet and t, b, τ, {ν_τ} are the S_3 singlet and further there are assumed S_3 doublet Higgs (H_1, H…

Generalized Covariant Derivative on Extra Dimension and Weinberg-Salam Model

Yoshitaka Okumura

The generalized covariant derivative on 5-dimen-sional space including 1-dimensional extra compact space is defined, and, by use of it, the Weinberg-Salam model is reconstructed. T…

Noncommutative gauge theory with the symmetry and standard-like model with fractional charges

Yoshitaka Okumura

gauge field theory on noncommutative spacetime is formulated and the standard-like model with the symmetry ${\text{U}(3_c\otimes 2\otimes 1_{\text{\scriptsize$Y…

A Dynamical Interpretation of Connes' Unimodularity Condition in Standard Model and Majorana Neutrino

Katsusada Morita, Yoshitaka Okumura

Standard model is minimally extended using the unitary group of Connes' color-flavor algebra. In place of Connes' unimodularity condition an extra…

Lorentz covariant field theory on noncommutative spacetime based on DFR algebra

Yoshitaka Okumura

Lorentz covariance is the fundamental principle of every relativistic field theory which insures consistent physical descriptions. Even if the space-time is noncommutative, field t…

Noncommutative gauge theory with arbitrary U(1) charges

Yoshitaka Okumura

It is well-known that the charge of fermion is 0 or in the U(1) gauge theory on noncommutative spacetime. Since the deviation from the standard model in particle physics has…
