Particle Ratio Fluctuations in NA49
The results of the NA49 energy scan program show a sharp maximum of the ratio of K + to !+ yields in central Pb+Pb collisions at beam energies of 20-30 AGeV. This observation has been interpreted as an indication of a phase transition at low SPS energies. We present results on energy dependence of e...
