“…Two paths towards the quark phase of matter started in parallel in 1964-65, when on one hand quarks were introduced triggering the first quark matter paper [117], and on another, Hagedorn recognized that the yields and spectra of hadrons were governed by new physics involving T H and he proposed the SBM [11]. This briefly addresses the events surrounding Hagedorn discovery and the resulting modern theory of hot hadronic matter.…”

Melting Hadrons, Boiling Quarks - From Hagedorn Temperature to Ultra-Relativistic Heavy-Ion Collisions at CERN

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 The material of this review is complemented by two early and unpublished reports containing the prediction of the different forms of hadron matter, and of the formation of QGP in relativistic heavy ion collisions, including the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.

“…Quark-star models [117] appear as soon as quarks are proposed; "after" gluons join quarks [118], within a year -Peter Carruthers in 1973/74 [119] recognized that dense quark matter would be a quite "bizarre" plasma and he explores its many body aspects. His paper has priority but is also hard to obtain, published in a new journal that did not last.…”

“…Ivanenko and Kurdgelaidze [8], Itoh [9] and Collins and Perry [10] suggested that quasi-free quarks may exist in the centre of neutron stars. Many physicists started to speculate that the QGP can be formed in nucleus-nucleus collisions at high energies and thus it may be discovered in laboratory experiments.…”

A brief history of the observation of the onset of deconfinement-the beginning of the creation of quark-gluon plasma in nucleus-nucleus collisions with increasing collision energy-is presented. It starts with the measurement of the hadron mass spectrum and Hagedorn's hypothesis of the limiting temperature of hadronic matter (the Hagedorn temperature). Then the conjecture that the Hagedorn temperature is the phase transition temperature was formulated with the crucial Hagedorn participation. It was confirmed by the observation of the onset of deconfinement in lead-lead collisions at the CERN SPS energies. Hadron Mass Spectrum and the Hagedorn TemperatureA history of multi-particle production started with the discoveries of hadrons, first in cosmic-ray experiments and soon after in experiments using beams of particles produced in accelerators. Naturally, the first hadrons, discovered in collisions of cosmic-ray particles, were the lightest ones, pion, kaon and . With the rapid advent of particle accelerators new particles were uncovered almost daily. About 1,000 hadronic states are known so far. Their density in mass .m/ increases approxi-
