The strong-correlations puzzle

The CP Puzzle in the Strong Interactions∗

This lecture, directed to an broad audience including non-specialists, presents a short review of the problem of strong CP symmetry maintenance. The problem is defined and the possible solutions briefly reviewed. I discuss the way in which Roberto Peccei and I came up with one solution, generally known as Peccei-Quinn symmetry.

Strong correlations in hot QCD

After reviewing briefly the basic strategy of analyzing the RHIC data, recent lattice results of the non-pertubative/strong-coupling aspects of quark-gluon plasma probed primarily by the heavy quarks are presented. In particular, free energies of static quarks in various color channels, the Debye screening mass and the spatial string tension above the pseudo-critical temperature are discussed o...
