Description
I look back at the early results of S+S collisions at 200 A GeV and related theoretical data analysis of more than 20 years ago, and compare these results with those we have since obtained in Pb-Pb reactions at SPS and LHC. The key signatures, strangeness and multistrange antibaryons, as well as entropy content of this small system do indicate development of conditions that are today associated with the formation of quark-gluon deconfined phase of matter. The forthcoming experimental effort to characterize the threshold of QGP formation as a function of collisions energy and reaction volume will be placed into strangeness and entropy context.
