Analytic construction of sphaleron-like solution invoking higher dimensional gauge theory
Yuki Adachi, C. S. Lim, Nobuhito Maru
We perform analytic construction of a sphaleron-like solution in the 4-dimensional (4D) space-time invoking the framework of 5D SU(2) gauge theory. By the sphaleron-like solution w…
On the vacuum structure of gauge-Higgs unification models
Yuki Adachi, C. S. Lim, Nobuhito Maru
In this paper, we discuss the vacuum structure of the gauge-Higgs unification theory, which is one of the attractive candidates of physics beyond the standard model. This scenario…
The strong CP problem and higher dimensional gauge theories
Yuki Adachi, C. S. Lim, Nobuhito Maru
We discuss a natural scenario to solve the strong CP problem in the framework of the higher dimensional gauge theory. An axion-like field has been built-in as the extra-space…
Higgs-Inflaton Potential in Higher-Dimensional SUSY Gauge Theories
Takeo Inami, Yoji Koyama, C. S. Lim +1
We study the possibility that the Higgs and the inflaton are the same single field or cousins arising from the extra space components of some higher-dimensional gauge field. We tak…
Gauge-Fixing and Residual Symmetries in Gauge/Gravity Theories with Extra Dimensions
C. S. Lim, Tomoaki Nagasawa, Satoshi Ohya +2
We study compactified pure gauge/gravitational theories with gauge-fixing terms and show that these theories possess quantum mechanical SUSY-like symmetries between unphysical degr…
Supersymmetry in 5d Gravity
C. S. Lim, Tomoaki Nagasawa, Satoshi Ohya +2
We study a 5d gravity theory with a warped metric and show that two N = 2 supersymmetric quantum-mechanical systems are hidden in the 4d spectrum. The supersymmetry can be regarded…
Supersymmetry in gauge theories with extra dimensions
C. S. Lim, Tomoaki Nagasawa, Makoto Sakamoto +1
We show that a quantum-mechanical N=2 supersymmetry is hidden in 4d mass spectrum of any gauge invariant theories with extra dimensions. The N=2 supercharges are explicitly constru…
The Gauge Hierarchy Problem and Higher Dimensional Gauge Theories
H. Hatanaka, T. Inami, C. S. Lim
We report on an attempt to solve the gauge hierarchy problem in the framework of higher dimensional gauge theories. Both classical Higgs mass and quadratically divergent quantum co…
CP in Orbifold Models
T. Kobayashi, C. S. Lim
We study CP in orbifold models. It is found that the orbifolds always have some automorphisms as CP symmetry. The symmetries are restricted non-trivially due to geometrical structu…
