    "abstract": "It is shown that data on pion and strangeness production in central\nnucleus-nucleus collisions are consistent with the hypothesis of a Quark Gluon\nPlasma formation between 15 A GeV/c (BNL AGS) and 160 A GeV/c (CERN SPS)\ncollision energies. The experimental results interpreted in the framework of a\nstatistical approach indicate that the effective number of degrees of freedom\nincreases by a factor of about 3 in the course of the phase transition and that\nthe plasma created at CERN SPS energy may have a temperature of about 280 MeV\n(energy density $\\approx$ 10 GeV/fm^3). Experimental studies of central Pb+Pb\ncollisions in the energy range 20-160 A GeV/c are urgently needed in order to\nlocalize the threshold energy, and study the properties of the QCD phase\ntransition.",
