This diagnostic can be extracted theoretically from lattice QCD calculations and experimentally from event-by-event fluctuations. The analysis of present lattice results above the critical temperature severely limits the presence of q-qbar bound states, thus supporting a picture of independent (quasi)quarks.4 pages, 2 eps figures, Revised: several sign typos have been fixed (the PRL version is correct)Nuclear TheoryHigh Energy Physics - PhenomenologyNuclear Experimenttext
