Abstract
In this letter we show that most of the fluctuations in particle densities observed in relativistic heavy-ion collisions are consistent with stochastic emission, i.e., most of the correlations between produced particles are washed out due to the vast number of particles in the environment. We further explore the general trends by investigating different systems, energies and centrality cuts. Comparisons with the Fritiof model show that string fragmentation gives results similar to the data.
