Query: Impact of resonance regeneration and decay on the net-proton
  fluctuations in a hadron resonance gas   We investigate net-proton fluctuations as important observables measured in
heavy-ion collisions within the hadron resonance gas (HRG) model. Special
emphasis is given to effects which are a priori not inherent in a thermally and
chemically equilibrated HRG approach. In particular, we point out the
importance of taking into account the successive regeneration and decay of
resonances below the chemical freeze-out, which lead to a randomization of the
isospin of nucleons and thus to additional fluctuations in the net-proton
number. We find good agreement between our model results and the recent STAR
measurements of the higher-order moments of the net-proton distribution.
