“…The first preliminary NA61 results from p + p interactions [61,63] Other fluctuation measures were studied both by SPS and RHIC experiments, but the general conclusion is that the energy dependence of fluctuations for heavy-ion collisions (Pb + Pb/Au + Au) does not show any effects that can be attributed to CP. NA49 and NA61 did not find any possible signatures of CP when studying the energy dependence (Pb + Pb and also p + p collisions) of chemical (particle type) fluctuations [51,53,64,65]. Also, electric charge [66] and azimuthal angle [64] fluctuations in central Pb+Pb data did not show any unexpected behaviour.…”

Also, electric charge [66] and azimuthal angle [64] fluctuations in central Pb+Pb data did not show any unexpected behaviour. The RHIC BES studied: netcharge and net-proton fluctuations [67], p T correlations, particle ratio (chemical) fluctuations [68], but again, within the uncertainties, no clear non-monotonic behaviour, and thus no clear evidence of CP in the energy scan of Au + Au collisions was observed.…”

The recent results on relativistic heavy-ion collisions are discussed. The most convincing quarkgluon plasma signatures at the LHC and the top RHIC energies are presented. Moreover, the possible methods of evaluating the energy threshold for deconfinement (onset of deconfinement) are described, and the corresponding results from the RHIC Beam Energy Scan and the SPS programs are shown. Additionally, the first signatures of creating dense and collectively behaving systems in collisions of small nuclei (or even in elementary interactions) are discussed. Finally, the current status of experimental search for the critical point of strongly interacting matter is summarized.

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

View full text Add to dashboard Cite

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.
