High Temperature QCD and Dimensional Reduction
Bengt Petersson
TL;DR
This paper discusses lattice results for high-temperature QCD, explains the dimensional reduction technique for studying quark-gluon plasma, and presents new tests of this method in a simplified three-dimensional gauge theory.
Contribution
It introduces and tests the dimensional reduction technique in a simplified model to validate its effectiveness for studying high-temperature QCD.
Findings
Dimensional reduction effectively captures long-distance properties in a 3D gauge theory.
Lattice results provide insights into QCD behavior at finite temperature.
New tests support the validity of dimensional reduction in simplified models.
Abstract
In this talk I will first give a short discussion of some lattice results for QCD at finite temperature. I will then describe in some detail the technique of dimensional reduction, which in principle is a powerful technique to obtain results on the long distance properties of the quark-gluon plasma. Finally I will describe some new results, which test the technique in a simpler model, namely three dimensional gauge theory.
