We investigate net-proton fluctuations as important observables measured inheavy-ion collisions within the hadron resonance gas (HRG) model. Specialemphasis is given to effects which are a priori not inherent in a thermally andchemically equilibrated HRG approach. In particular, we point out theimportance of taking into account the successive regeneration and decay ofresonances below the chemical freeze-out, which lead to a randomization of theisospin of nucleons and thus to additional fluctuations in the net-protonnumber. We find good agreement between our model results and the recent STARmeasurements of the higher-order moments of the net-proton distribution.
