Abstract: It is shown that the hadronic phase in ultra-relativistic heavy ion collisions can be used to understandthe properties of the f0(980) resonance. In particular it is shown that the centrality dependence of the f0(980)/π andf0(980)/φ ratios depends strongly on the f0(980) → K + K branching ratio and whether the f0(980) is produced as a |qq〉or |ss〉state. These conclusions are drawn from calculations within the partial chemical equilibrium of the HRG model within Thermal-FIST as well as with the fully non-equilibrium hybrid-transport approach UrQMD. Our findings show how the hadronic phase in heavy ion collisionscan be used for studies of exotic hadron properties otherwise possible only in dedicated experiments such as PANDA.
