A global assessment of the Strangeness including-Statistical Bootstrap   Model analysis of nucleus-nucleus and proton-antiproton interactions
  A strangeness and isospin asymmetry including statistical bootstrap model analysis of the multiparticle system produced in the Pb+Pb collision at 158 AGeV at CERN is presented. It is concluded that this interaction process has not crossed the deconfinenent line. Direct comparisons with the results of similar analyses pertaining to nucleus-nucleus and proton-antiproton collisions at CERN are made. The overall picture points to the S+S collision at 200 AGeV as a prime candidate of a process which has crossed the border separating the hadronic from the deconfined phase of matter.
