Propagators of hot SU(2) gauge theory from 3d adjoint Higgs model

Abstract: We study the Landau gauge propagators of the lattice $SU(2)$ 3d adjoint Higgs model, considered as an effective theory of high temperature 4d $SU(2)$ gauge theory. From the long distance behaviour of the propagators we extract the screening masses. It is shown that the pole masses extracted from the propagators in 3d effective theory agree well with the screening masses obtained recently in finite temperature SU(2) theory. In so-called $lambda$ gauges the gauge dependence of the screening masses defined throgh the poles of the corresponding propagators is discussed. Some preliminary results were published in Karsch et al, Phys. Lett. B442 (1998) 291
