WebbIn particular, the HADES data point shows a large proton scaled variance of κ 2/κ 1 > 2, warranting a closer look at these data. Proton number cumulants in Au-Au collisions at √ s NN = 2.4 GeV have recently been analysed in [32] in the framework of Siemens-Rasmussen-like fireball model, with freeze-out parameters based on Refs. [33, 34]. Webbpoint in frozen state was shown by above eq. (8).This equation was essentially based on the Arrhenius formula and new simulation equation of freezing point depression. Eq. (8) were derived by taking into account of the concentration effect caused on freezing the solution. The reaction in liquid state, however, follows eq. (9).--=Ao*&,*t*expd ...
