Debye Screening in the Qcd Plasma
نویسنده
چکیده
Various definitions for the QCD Debye mass and its evaluation are reviewed in a non-perturabtive framework for the study of screening of general static sources. While it is possible to perturbatively integrate over scales ∼ T and thus construct a 3d effective theory, the softer scales ∼ gT and ∼ gT are strongly coupled for temperatures < ∼ 10 GeV and require lattice simulations. Within the effective theory, a lattice treatment of screening at finite quark densities μ< ∼ 4/T is also possible.

Debye screening in strongly coupled N = 4 supersymmetric Yang-Mills plasma
Using the AdS/CFT correspondence, we examine the behavior of correlators of Polyakov loops and other operators in N =4 supersymmetric Yang-Mills theory at non-zero temperature. The implications for Debye screening in this strongly coupled non-Abelian plasma, and comparisons with available results for thermal QCD, are discussed.
متن کاملRunning coupling and screening in the (s)QGP
Emphasizing the importance of renormalization in the context of thermal field theory it is pointed out that the Debye mass in the hot quark gluon plasma is determined by the coupling at the scale mD, not T as commonly presumed. The mended result agrees quantitatively with lattice QCD calculations in the strong coupling regime almost down to Tc.
متن کاملNext-to-leading order Debye mass for the quark-gluon plasma.
The Debye screening mass for a quark-gluon plasma at high temperature is calculated to next-to-leading order in the QCD coupling constant from the correlator of two Polyakov loops. The result agrees with the screening mass defined by the location of the pole in the gluon propagator as calculated by Rebhan. It is logarithmically sensitive to nonperturbative effects associated with the screening ...

We study the non-abelian, gauge invariant, screening potential between two charges in a quark-gluon plasma. Using Braaten and Pisarski resummed perturbation theory in temporal axial gauge, we find a repulsive power screened potential which behaves as ∼ 1/r 6 at large distance. This questions either the physical meaning of the Debye mass or the known pragmatic treatment of the temporal axial gau...
متن کاملE ects of Screening on Quark - Antiquark Cross Sections in Quark - Gluon Plasma
Lowest-order cross sections for q q production and annihilation can be approximately corrected for higher-order QCD e ects by using a corrective Kfactor. For energies where quark masses cannot be ignored, the K-factor is dominated by the wave function distortion arising from the initialor nalstate interaction between the quark and the antiquark. We evaluate this Kfactor for q q production and a...
