The spatial string tension and dimensional reduction in QCD.

Presenter: Jack Liddle — Universitaet Bielefeld

RBC Bielefeld Collaboration

The spatial string tension for 3+1 dimensional QCD at finite temperature is measured. The gauge configurations were generated with two light and one heavier strange quark on lattices of size 163 4 and 243 6. This spatial string tension is compared with the string tension of the 3 dimensional pure gauge theory together with the temperature dependent 2-loop running coupling. Further comparison is made with predictions from dimensionally reduced effective theories.
