Complex poles, spectral function and reflection positivity violation of Yang-Mills theory
Kei-Ichi Kondo, Yui Hayashi, Ryutaro Matsudo +2
We discuss the analytic continuation of the gluon propagator from the Euclidean region to the complex squared-momentum plane towards the Minkowski region from a viewpoint of gluon…
Quark confinement in the Yang-Mills theory with a gauge-invariant gluon mass in view of the gauge-invariant BEH mechanism
Akihiro Shibata, Kei-Ichi Kondo, Ryutaro Matsudo +1
In order to clarify the mechanism of quark confinement in the Yang-Mills theory with mass gap, we propose to investigate the massive Yang-Mills model, namely, Yang-Mills theory wit…
How to extract the "Abelian" part of double-winding Wilson loop
Ryutaro Matsudo
It is known that the naive Abelian Wilson loop defined by the Abelian projection cannot reproduce the correct behavior of the double-winding Wilson loop. It is also known that the…
Correct way to extract dominant part of the Wilson loop in higher representations
Ryutaro Matsudo, Akihiro Shibata, Seikou Kato +1
The Abelian dominance for the string tension was shown for the fundamental sources in MA gauge in the lattice simulations. For higher representations, however, it is also known tha…
Confinement of quarks in higher representations in view of dual superconductivity
Akihiro Shibata, Ryutaro Matsudo, Seikou Kato +1
Dual superconductor picture is one of the most promising scenarios for quark confinement. We have proposed a new formulation of Yang-Mills theory on the lattice so that the so-call…
