High temperature phase of QCD

Abstract

I give a brief overview of our present understanding of the high temperature phase of QCD, trying to clarify some of the theoretical issues involved in the current discussions that emphasize the strongly coupled character of the quark-gluon plasma produced at RHIC.

To appear in the proceedings of the International Conference on Strong & Electroweak Matter, BNL, May 10-13 (2006), to be published in Nucl. Phys. A 9 pages, 3 figures - late submission to the Archive
