“…Of course we were looking at central rapidity i.e. CM system, quite different from the work of Anishetty et al [133]. Hagedorn explains the time line of our and related work in his 1984 review [13].…”

“…It is regrettable that once Chapline-Kerman ran into resistance they did not pursue the publication, and/or further development of their idea; instead, a) A year later, Kerman (working with Chin who gave him the credit for the QGP-RHI connection idea in his paper), presents strangelets [131], cold drops of quark matter containing a large strangeness content. b) And a few years later, Chapline [132] gives credit for the quark-matter connection to RHI collisions both to Chapline-Kerman [125] work, and the work of Anishetty, Koehler, and McLerran of 1980 [133]. Anishetty et al claim in their abstract .…”

“…The geometric collision time thus is cτ 0 = 12 fm as measured by an observer comoving with one of the nuclei. Thus if you are interested like Anishetty et al [133] in hot projectile and target nuclei there is no doubt this is one of the outcomes of the collision.…”

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 The material of this review is complemented by two early and unpublished reports containing the prediction of the different forms of hadron matter, and of the formation of QGP in relativistic heavy ion collisions, including the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 leading consideration was to achieve a "clean" central rapidity region, i.e., with small net baryon density. Experiments at the ISR indicated that the projectile and target fragmentation regions in pp collisions were two units of rapidity wide; nuclear effects were expected possibly to double this number [24]. Thus a lower bound on the energy would be 50 GeV/A per beam.…”

This talk traces the history of RHIC over the last two decades, reviewing the scientific motivations underlying its design, and the challenges and opportunities the machine presents. THE VERY EARLY DAYSThe opening of RHIC culminates a long history of fascination of nuclear and high energy physicists with discovering new physics by colliding heavy nuclei at high energy. As far back as the late 1960's the possibility of accelerating uranium ions in the CERN ISR for this purpose was contemplated [1]. The subject received "subtle stimulation" by the workshop on "Bev/nucleon collisions of heavy ions" at Bear Mountain, New York, organized by Arthur Kerman, Leon Lederman, Mal Ruderman, Joe Weneser and T.D. Lee in the fall of 1974 [1]. In retrospect, the Bear Mountain meeting was a turning point in bringing heavy ion physics to the forefront as a research tool. The driving question at the meeting was, as Lee emphasized, whether the vacuum is a medium whose properties one could change; "we should investigate," he pointed out, ". . . phenomena by distributing high energy or high nucleon density over a relatively large volume." If in this way one could restore broken symmetries of the vacuum, then it might be possible to create abnormal dense states of nuclear matter, as Lee and Gian-Carlo Wick speculated [2].The physics discussions at Bear Mountain focussed on astrophysical implications of unusual states of matter such as pion condensates and Lee-Wick matter in neutron stars, high energy cosmic rays, stable abnormal nuclei, as well as fanciful applications, e.g., by A. Turkevich to manufacture and custom tailor superheavy materials, even to make a high temperature superconductor, and by G. Vineyard to use abnormal nuclei as active components in a breeder reactor. The worry engendered by the latter's suggestion that seeds of unusual states could set off a global catastrophe was calmed by the observation that "Lee-Wick theory indicates that 10 8 or 10 9 [abnormal superdense nuclei] have already been produced on the moon, and that the moon is still there, albeit with large holes" -an approach still invoked to support the safety of high energy nuclear collisions [3]. Schemes for accelerating heavy ion beams were also addressed: H. Grunder described possibilities of injecting heavy beams from the SuperHILAC into the Bevalac (a project in fact completed in 1984), G. Cocconi mentioned thoughts at CERN of transferring ions up to 16 O from the PS into the ISR and eventually into the SPS [4]. Most important for RHIC was K. Prelec and A. van Steenbergen's proposal of constructing a booster ring to inject fully stripped ions with A ≥ 200 into the AGS.

“…Since the projectile is assumed highly relativistic (c => 1), the position where the particle is emitted is z(y) - Beyond that point, nuclei pass through each other although they do get compressed to ~(4-5)p Q in the porcess. 48,44 The energy density, in contrast to the baryon density.continues to increase with energy as we shall see in the next section.…”
