Gluon and ghost propagators at small temperatures in Landau gauge Yang-Mills theory — •Burghard Grueter¹, Axel Maas², Reinhard Alkofer¹, and Jochen Wambach² — ¹Institut für Theoretische Physik, U Tübingen — ²Institut für Kernphysik, TU Darmstadt

The infrared behavior of the gluon and ghost propagators in Landau gauge Yang-Mills theory is investigated at non-vanishing temperatures.

We generalize a truncation scheme of Dyson-Schwinger equations for these propagators which has been applied successfully at zero temperature [1].

Hereby we focus on an extension of the corresponding numerical techniques for the confined phase, i. e. for small temperatures. The thus obtained first results will be presented and their implications for the same approach to the high temperature limit [2] will be discussed.
