Gluons at finite temperature in Landau gauge Yang–Mills theory
The infrared behavior of Yang-Mills theory at finite temperature provides access to the role of confinement. In this review recent results on this topic from lattice calculations and especially Dyson–Schwinger studies are discussed. These indicate persistence of a residual confinement even in the high–temperature phase. The confinement mechanism is very similar to the one in the vacuum for the ...
متن کاملFinite-Temperature Yang-Mills Theory in Landau Gauge
The gluon and ghost propagators in Landau Gauge Yang-Mills Theory are investigated. Self-consistent solutions are obtained from their equations of motion above and below the presumed phase transition. Gluon confinement is manifest in these solutions and can be read off the infrared behavior of the gluon and ghost propagators. Confinement prevails below the presumed phase transition. Above and i...
متن کاملPropagators of 2d Landau-gauge Yang-Mills theory
In two-dimensional Yang-Mills theory many quantities can be determined exactly. In particular, no propagating modes exist, and thus the theory is perfectly confining. It is also related to topological field theories [1]. In Landau gauge, this is manifest already in perturbation theory, where one has an explicit version of Kugo-Ojima confinement by the quartet mechanism [2]. On the other hand, t...
متن کاملHigh-Temperature Limit of Landau-Gauge Yang-Mills Theory
The infrared properties of the high-temperature limit of Landau-gauge Yang-Mills theory are investigated. In a first step the high-temperature limit of the Dyson-Schwinger equations is taken. The resulting equations are identical to the Dyson-Schwinger equations of the dimensionally reduced theory, a three-dimensional Yang-Mills theory coupled to an effective adjoint Higgs field. These equation...
متن کاملThe Ghost-Gluon Vertex in Landau Gauge Yang-Mills Theory
Possible mechanisms for gluon confinement in Yang-Mills theory in covariant gauges are discussed briefly. Implications for the infrared behavior of the Green’s functions are outlined. Results for the gluon and Faddeev-Popov ghost propagators from DysonSchwinger studies and lattice calculations are presented. The importance of the ghostgluon vertex in these studies is discussed. Numerical result...
