SU(9) grand unified model with rank-reducing discrete boundary conditions on
Yoshiharu Kawamura, Kentaro Kojima, Toshifumi Yamashita
We study a six-dimensional SU(9) grand unified model with rank-reducing discrete boundary conditions and continuous Wilson line phases on the orbifold . We show th…
Mass spectrum in a six-dimensional gauge theory on a magnetized torus
Kentaro Kojima, Yuri Okubo, Carolina Sayuri Takeda
We examine six-dimensional gauge theories compactified on a two-dimensional torus with a constant magnetic flux background to obtain a comprehensive low-energy mass spectru…
Grand Gauge-Higgs Unification on via Diagonal Embedding Method
Kentaro Kojima, Kazunori Takenaga, Toshifumi Yamashita
We study a novel six-dimensional gauge theory compactified on the orbifold utilizing the diagonal embedding method. The bulk gauge group is ,…
On representation matrices of boundary conditions in gauge theories compactified on two-dimensional orbifolds
Yoshiharu Kawamura, Eiji Kodaira, Kentaro Kojima +1
We study the existence of diagonal representatives in each equivalence class of representation matrices of boundary conditions in or gauge theories compactified on t…
Early Dark Energy from a Higher-dimensional Gauge Theory
Kentaro Kojima, Yuri Okubo
The Hubble constant estimated from the CMB measurements shows large disagreement with the locally measured value. This inconsistency is called the Hubble tension and is vastly stud…
Ultradiscrete limit of the spectral polynomial of the -Heun equation
Kentaro Kojima, Tsukasa Sato, Kouichi Takemura
It is known that the q-Heun equation has polynomial-type solutions in some special cases, and the condition for the accessory parameter E is described by the roots of the spectral…
