5d Dirac fermion on quantum graph

Yukihiro Fujimoto, Tomonori Inoue, Makoto Sakamoto +2

In this paper, we investigate a five-dimensional Dirac fermion on a quantum graph that consists of a single vertex and $N$ loops. We find that the model possesses a rich structure…

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 $d + 2$ ( $d + 1$ ) supercharges…

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 $N = 2$ quantum-mechanical supersymmetry is hidden in the four-dimensio…

Dynamical generation of fermion mass hierarchy in an extra dimension

Yukihiro Fujimoto, Takashi Miura, Kenji Nishiwaki +1

We propose a new mechanism to produce a fermion mass hierarchy dynamically in a model with a singlet generation of fermions. A five dimensional gauge theory on an interval with poi…

Supersymmetry in 6d Dirac Action

Yukihiro Fujimoto, Kouhei Hasegawa, Kenji Nishiwaki +2

We investigate a 6d Dirac fermion on a rectangle. It is found that the 4d spectrum is governed by $N = 2$ supersymmetric quantum mechanics. Then we demonstrate that the supersymmetry…

6d Dirac fermion on a rectangle; scrutinizing boundary conditions, mode functions and spectrum

Yukihiro Fujimoto, Kouhei Hasegawa, Kenji Nishiwaki +2

We classify possible boundary conditions of a 6d Dirac fermion $Ψ$ on a rectangle under the requirement that the 4d Lorentz structure is maintained, and derive the profiles and spe…
