“…The observation of a strong enhancement of multistrange baryon and antibaryon emission in Pb+Pb collisions by experiment WA97 [24] formed an important pillar of the claim that evidence for a new state of matter had been found at the CERN-SPS [25]. The results were confirmed and extended to lower beam energies in recent years by the NA57 collaboration [26].…”

Abstract. In the context of the Hagedorn temperature half-centenary I describe our understanding of the hot phases of hadronic matter both below and above the Hagedorn temperature. The first part of the review addresses many frequently posed questions about properties of hadronic matter in different phases, phase transition and the exploration of quark-gluon plasma (QGP). The historical context of the discovery of QGP is shown and the role of strangeness and strange antibaryon signature of QGP illustrated. In the second part I discuss the corresponding theoretical ideas and show how experimental results can be used to describe the properties of QGP at hadronization. The material of this review is complemented by two early and unpublished reports containing the prediction of the different forms of hadron matter, and of the formation of QGP in relativistic heavy ion collisions, including the discussion of strangeness, and in particular strange antibaryon signature of QGP.

“…The figure shows that the correction varies from 10% to 30% and that the high momentum setting exhibits a distinct p t dependence. The RQMD model gives a fair account of the Λ cross sections measured by the NA49 and WA97 experiments [12,13] and the systematic errors introduced by the corrections of (3) are considerably smaller than the corrections themselves. …”

Abstract. Proton and deuteron production has been observed in S+S and S+Pb collisions at 200 A·GeV and in Pb+Pb reactions at 158 A·GeV at the CERN SPS accelerator. For Pb+Pb triton production was also measured. The p and d spectra as well as the p and t spectra were observed in similar rapidity ranges and over similar ranges of transverse momenta per nucleon, making it possible to interpret the cross sections of the composite particles in terms of coalescence mechanisms. Volumes of homogeneity were extracted and compared to pion-pair HBT interferometry results. Special attention is given to the dependence on transverse mass, centrality and rapidity.
