    "abstract": "We perform an analysis of preliminary data on hadron yields and fluctuations\nwithin the Statistical hadronization ansatz. We describe the theoretical\ndisagreements between different statistical models currently on the market, and\nshow how the simultaneous analysis of yields and fluctuations can be used to\ndetermine if one of them can be connected to underlying physics. We perform\nsuch an analysis on preliminary RHIC and SPS A-A data that includes particle\nyields, ratios and event by event fluctuations. We show that the equilibrium\nstatistical model can not describe the $K/\\pi$ fluctuation measured at RHIC and\nSPS, unless an unrealistically small volume is assumed. Such small volume then\nmakes it impossible to describe the total particle multiplicity. The\nnon-equilibrium model,on the other hand, describes both the $K/\\pi$ fluctuation\nand yields acceptably due to the extra boost to the $\\pi$ fluctuation provided\nby the high pion chemical potential. We show, however, that both models\nsignificantly over-estimate the $p/\\pi$ fluctuation measured at the SPS, and\nspeculate for the reason behind this.",
