“…Before these studies of strangeness enhancement were carried out within the central rapidity region by NA57 and WA97 experiments, it has been shown that central rapidity is indeed the kinematic domain where the new physics is occurring. The NA35II experiment obtained Λ yield for 200A GeV Sulfur projectile on laboratory Sulfur target [32,33]. As can be seen in figure 5, the antibaryon yields are localized in the central CM (center of momentum) rapidity region.…”

Abstract. A brief summary of strangeness mile stones is followed by a chemical non-equilibrium statistical hadronization analysis of strangeness results at SPS and RHIC. Strange particle production in AA interactions at √ s NN ≥ 8.6 GeV can be understood consistently as originating from the deconfined quark-gluon plasma in a sudden hadronization process. Onset of QGP formation as function of energy is placed in the beam energy interval 10-30A GeV/c. Strangeness anomalies at LHC are described.

Abstract. We analyse multiparticle production in a thermal framework for seven central nucleus + nucleus collisions, e + + e − annihilation into hadrons on the Z resonance and four hadronic reactions (p + p and p + p with partial centrality selection), with centre of mass energies ranging from √ s = 2.6 GeV (per nucleon pair) to 1.8 TeV. Thermodynamic parameters at chemical freezeout (temperature and baryon and strangeness fugacities) are obtained from appropriate fits, generally improving in quality for reactions subjected to centrality cuts. All systems with non-vanishing fugacities are extrapolated along trajectories of equal energy density, density and entropy density to zero fugacities. The so-obtained temperatures extrapolated to zero fugacities as a function of initial energy density ε in universally show a strong rise followed by a saturating limit of T lim = 155 ± 6 ± 20 MeV. We interpret this behaviour as mapping out the boundary between quark gluon plasma and hadronic phases. The ratio of strange antiquarks to light ones as a function of the initial energy density ε in shows the same behaviour as the temperature, saturating at a value of 0.365 ± 0.033 ± 0.07. No distinctive feature of 'strangeness enhancement' is seen for heavy ion collisions relative to hadronic and leptonic reactions, when compared at the same initial energy density.

In continuation of our perusal of the studies on transverse momentum spectra for the main varieties of secondaries from a consistent and comprehensive phenomenological approach, we propose to take up here -after a successful completion of reporting in detail the results (Ref. [4] in the text) on our analyses of the p T -spectra of pions -the studies specially on production of kaons, protons and antiprotons in several proton-induced and nucleus-involved collisions at high energies.The measured data on inclusive cross sections of kaons, protons and antiprotons from the various published sources have here been assorted first. Next, data on the p T -spectra of the specific secondaries produced in P P and PP reactions have been scanned and analyzed with the help of Hagedorn's model(HM). Thereafter a connector, named here the combinational approach(CA), hasbeen constructed and used to analyze the data on p T -spectra of some major category of non-pion secondaries produced in nucleus-nucleus(AA/AB) collisions at high energies. And these exercises have, finally, led to the modestly successful interpretations of a wide band of data with the revelation of some insightful physical aspects of high energy interactions. The limitations of the approach have also been precisely pointed out in the end.PACS numbers: 25.75.-q, 13.60.Hb.
