Effect of resonance decays on net-kaon fluctuations

We compare the mean-over-variance ratio of the net-Kaon distribution calculated with a hadron resonance gas model to the experimental data from the STAR collaboration.

The theoretical ratios are calculated through Monte Carlo simulations, to best capture the probabilistic nature of particle decays. Freeze-out parameters previously obtained in the literature are used as inputs. By comparing our results to the experimental data, we are able to quantify the effect of probabilistic resonance decays.
