Double-winding Wilson loops in SU(N) lattice Yang-Mills gauge theory
Seikou Kato, Akihiro Shibata, Kei-Ichi Kondo
We study double-winding Wilson loops in lattice Yang-Mills gauge theory by using both strong coupling expansions and numerical simulations. First, we examine how the area l…

Complex poles and spectral functions of Landau gauge QCD and QCD-like theories
Yui Hayashi, Kei-Ichi Kondo
In view of the expectation that the existence of complex poles is a signal of confinement, we investigate the analytic structure of the gluon, quark, and ghost propagators in the L…
