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…
How to extract the dominant part of the Wilson loop average in higher representations
Ryutaro Matsudo, Akihiro Shibata, Seikou Kato +1
In previous works, we have proposed a new formulation of Yang-Mills theory on the lattice so that the so-called restricted field obtained from the gauge-covariant decomposition pla…
Reflection positivity and complex analysis of the Yang-Mills theory from a viewpoint of gluon confinement
Kei-Ichi Kondo, Masaki Watanabe, Yui Hayashi +2
In order to understand the confining decoupling solution of the Yang-Mills theory in the Landau gauge, we consider the massive Yang-Mills model which is defined by just adding a gl…
