1. Complex poles and spectral function of Yang-Mills theory / Hayashi, Yui ; Kondo, Kei-Ichi
We derive general relationships between the number of complex poles of a propagator and the sign of the spectral function originating from the branch cut in the Minkowski region under some assumptions on the asymptotic behaviors of the propagator. [...]

2. Magnetic monopoles in pure Yang–Mills theory with a gauge-invariant mass / Nishino, Shogo ; Matsudo, Ryutaro ; Warschinke, Matthias ; Kondo, Kei-Ichi
In this paper, we show the existence of magnetic monopoles in the pure Yang–Mills theory when a gauge-invariant mass term is introduced. [...]

3. Gauge-independent Brout–Englert–Higgs mechanism and Yang–Mills theory with a gauge-invariant gluon mass term / Kondo, Kei-Ichi
For the Yang–Mills theory coupled to a single scalar field in the fundamental representation of the gauge group, we present a gauge-independent description of the Brout–Englert–Higgs mechanism by which massless gauge bosons acquire their mass. [...]

4. Composite operator and condensate in the SU(N) Yang-Mills theory with U(N1) stability group / Warschinke, Matthias ; Matsudo, Ryutaro ; Nishino, Shogo ; Shinohara, Toru ; et al
Recently, some reformulations of the Yang-Mills theory inspired by the Cho-Faddeev-Niemi decomposition have been developed in order to understand confinement from the viewpoint of the dual superconductivity. [...]

5. Gluon bound state and asymptotic freedom derived from the Bethe–Salpeter equation / Fukamachi, Hitoshi ; Kondo, Kei-Ichi ; Nishino, Shogo ; Shinohara, Toru
In this paper we study the two-body bound states for gluons and ghosts in a massive Yang–Mills theory which is obtained by generalizing the ordinary massless Yang–Mills theory in a manifestly Lorentz-covariant gauge. [...]
