Debye Screening at Finite Temperature , Revisited ∗ )

We present an alternative way to calculate the screening of the static potential between two charges in (non)abelian gauge theories at high temperatures. Instead of a loop expansion of a gauge boson self-energy, we evaluate the energy shift of the vacuum to order e 2 after applying an external static magnetic field and extract a temperature-and momentum-dependent dielectric permittivity. The Ha...

Phase Diagram and Debye Mass in Thermally Reduced Qcd

At temperatures well above the transition QCD admits a thermally reduced version in 3D, which reproduces the long distance physics. We analyze the phase diagram, point out the relevance of Z(3) symmetry in the location of the transition and suggest a way out to reconcile this with the data. Related to this symmetry is the existence of an observable, the Z(N) wall, or rather its 3D version, and ...

High-T QCD and dimensional reduction: measuring the Debye mass

We study the high-temperature phase of SU(2) and SU(3) QCD using lattice simulations of an effective 3dimensional SU(N) + adjoint Higgs -theory, obtained through dimensional reduction. We investigate the phase diagram of the 3D theory, and find that the high-T QCD phase corresponds to the metastable symmetric phase of the 3D theory. We measure the Debye screening mass mD with gauge invariant op...

Lattice QCD at finite temperature

In the last years, much effort has been paid to experimentally detect the quark-gluon plasma (QGP) in heavy-ion collisions. In these experiments, precise theoretical inputs about the nature of the transition and the equation of state (EOS) of QGP are indispensable to unambiguously identify the signal of QGP. Here, lattice QCD provides us with the most powerful method to compute thermodynamic pr...

Lattice QCD at finite temperature

In recent years considerable progress has been made in understanding QCD at finite temperature using lattice simulations. Calculations of bulk thermodynamic quantities have been done in the realistic case of 2+1 flavors with sufficiently small quark masses using different versions of improved staggered actions [ 1, 2, 3, 4, 5]. This reduces or can even eliminate the uncertainty of extrapolation...
