Symmetry and Z_2-Orbifolding Approach in Five-dimensional Lattice Gauge Theory (2009)
Ishiyama, K., Murata, M., So, H., Takenaga, K.
In a lattice gauge-Higgs unification scenario using a Z_2-orbifolded extra-dimension, we find a new global symmetry in a case of SU(2) bulk gauge symmetry. It is a global symmetry on sites in a fixed...
Two loop finiteness of Higgs mass and potential in the gauge-Higgs unification (2007)
Hosotani, Y., Maru, N., Takenaga, K., Yamashita, Toshifumi
The zero mode of an extra-dimensional component of gauge potentials serves as a 4D Higgs field in the gauge-Higgs unification. We examine QED on $M^4 \times S^1$ and determine the mass and potential...
On Gauge Symmetry Breaking via Euclidean Time Component of Gauge Fields (2007)
We study gauge theories with/without an extra dimension at finite temperature, in which there are two kinds of order parameters of gauge symmetry breaking. The one is the zero mode of the gauge field...
We study SU(N) supersymmetric Yang-Mills theory with massless adjoint matter defined on $M^3\otimes S^1$. The SU(N) gauge symmetry is broken maximally to $U(1)^{N-1}$, independent of the number of...
SUSY Breaking through Compactification (2000)

Sakamoto, M., Tachibana, M., Takenaga, K.
We propose a new spontaneous supersymmetry breaking mechanism, in which extra compact dimensions play an important role. To illustrate our mechanism, we study a simple model consisting of two chiral...
Softly Broken Supersymmetric Gauge Theories through Compactifications (1998)
Effects of boundary conditions of fields for compactified space directions on the supersymmetric gauge theories are discussed. For general and possible boundary conditions the supersymmetry is...
Profile of the Electroweak Bubble Wall (1996)
Funakubo, K., Kakuto, A., Otsuki, S., Takenaga, K., Toyoda, F.
We study the CP-violating bubble wall by solving the coupled equations of motion derived from the two-Higgs-doublet model for the moduli $\rho_i$ and phases $\theta_ i$ of the two scalars $(i=1,2)$...
Electroweak theory with two massless Higgs doublets is studied by solving renormalization group equations for coupling constants in one-loop approximation. A cutoff~$\Lambda$, at which one of quartic...

Funakubo, K., Kakuto, A., Otsuki, S., Takenaga, K., Toyoda, F.
In any scenario of the electroweak baryogenesis, the profile of the CP violating bubble wall, created at the first-order phase transition, plays an essential role. We attempt to determine it by...

Funakubo, K., Kakuto, A., Otsuki, S., Takenaga, K., Toyoda, F.
By treating CP-violating interaction of the electroweak bubble wall as a perturbative term, chiral charge flux through the bubble wall is estimated. It is found that the absolute value of the flux...
