't Hooft-Polyakov monopole and instanton-like topological solution in gauge-Higgs unification
K. Hasegawa, C. S. Lim
We consider 't Hooft-Polyakov monopole (TPM) as a topological soliton in the 5-dimensional (5D) theory of gauge-Higgs unification. This scenario provides a very natural framework t…
Dynamical generation of quark/lepton mass hierarchy in an extra dimension
Yukihiro Fujimoto, Kouhei Hasegawa, Kenji Nishiwaki +4
We show that the observed quark/lepton mass hierarchy can be realized dynamically on an interval extra dimension with point interactions. In our model, the positions of the point i…
Majorana neutrino masses in gauge-Higgs unification
K. Hasegawa
The theory that the extra-space component of the gauge field is identified with the standard model Higgs boson, is called the gauge-Higgs unification (GHU) scenario. We examine how…
Extended supersymmetry with central charges in higher dimensional Dirac action
Yukihiro Fujimoto, Kouhei Hasegawa, Kenji Nishiwaki +3
A new realization of extended quantum-mechanical supersymmetry (QM SUSY) with central extension is investigated. We first show that two different sets of () supercharges…
Majorana neutrino masses in the scenario of gauge-Higgs unification
K. Hasegawa, C. S. Lim
In this paper we consider possible mechanisms to generate small Majorana neutrino masses for active neutrinos in the scenario of gauge-Higgs unification, a candidate for physics be…
Extended supersymmetry in Dirac action with extra dimensions
Yukihiro Fujimoto, Kouhei Hasegawa, Kenji Nishiwaki +3
We investigate a new realization of extended quantum-mechanical supersymmetry. We first show that an quantum-mechanical supersymmetry is hidden in the four-dimensio…
