| contents | On the Infrared Behavior of Green´s Functions in Yang-Mills Theory Tereza Mendes Attilio Cucchieri Axel Maas Física, Astronomía y Matemáticas Yang Vertices Confinement Propagators Mills theory Non-perturbative properties of QCD, such as color confinement, are encoded in the infrared behavior ofcorrelation functions, e.g. propagators and vertices. Various analytic predictions have been suggested for thesequantities in various gauges. Here we numerically test these predictions using lattice gauge theory. In particular,we present results for the 2- and 3-point functions for SU(2) Landau-gauge Yang-Mills theory in three and infour dimensions. Special attention is paid to systematic finite-volume effects. The gluon and ghost propagatorsare also evaluated in the so-called interpolating gauge (between the Landau and the Coulomb gauge), in orderto study their gauge-dependence. Finally, we consider these propagators in Landau gauge at finite temperature,with the aim of understanding the effect of the deconfinement phase transition on their infrared behavior. Allour results are compatible with the so-called Gribov-Zwanziger confinement scenario. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437210 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.1B Vol.37 |
