Propagators of Hot Su(2) Gauge Theory from 3d Adjoint Higgs Model *

چکیده
We study propagators of the lattice 3d adjoint Higgs model, considered as an effective theory of 4d SU (2) gauge theory at high temperature. The propagators are calculated in so-called λ-gauges. From the long distance behaviour of the propagators we extract the screening masses. It is shown that the pole masses extracted from the propagators agree well with the screening masses obtained recently in finite temperature SU (2) theory. The gauge dependence of the screening masses is also discussed.

Screening Masses of Hot Su(2) Gauge Theory from the 3d Adjoint Higgs Model
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.

متن کاملScreening in Hot SU(2) Gauge Theory and Propagators in 3d Adjoint Higgs model
We investigate the large distance behavior of the electric and magnetic propagators of hot SU(2) gauge theory in different gauges using lattice simulations of the full 4d theory and the effective, dimensionally reduced 3d theory. A comparison of the 3d and 4d data for the propagators suggests that dimensional reduction works surprisingly well down to temperatures T ∼ 2Tc. A detailed study of th...
متن کاملStatic Mass Scales in Hot Gauge Theories
The static sectors of the electroweak Standard Model and QCD at finite temperatures are described by 3d SU(N) Higgs models with scalars in the fundamental and adjoint representation, respectively. I summarize the non-perturbative physics of these theories like mass spectrum, string tension, screening of the static potential and non-perturbative corrections to the Debye mass, as obtained from re...
متن کاملTheory and Finite Temperature
We study to what extent the three-dimensional SU(N) + adjoint Higgs theory can be used as an effective theory for finite temperature SU(N) gauge theory, with N = 2, 3. The parameters of the 3d theory are computed in 2-loop perturbation theory in terms of T /Λ MS , N, N f. The perturbative effective potential of the 3d theory is computed to two loops for N = 2. While the Z(N) symmetry probably d...
متن کاملVortex solutions in SU(N ) adjoint Higgs theories
A relationship between vortex solutions in SU(N) gauge theories with two or more adjoint representation Higgs bosons and thick vortices of Center Vortex Theory is shown to exist. There is a similar relationship between monopole solutions of SU(N) gauge theories with a single adjoint representation Higgs boson and monopoles in Abelian Projection. New vortex solutions, relevant in central gauge f...
