Some Considerations concerning the Fluctuation of the Ratios of two Observables
Michael Hauer, Sascha Vogel
We discuss several possible caveats which arise with the interpretation of measurements of fluctuations in heavy ion collisions. We especially focus on the ratios of particle yield…
Statistical Fluctuations and Correlations in Hadronic Equilibrium Systems
Michael Hauer
This thesis is dedictaed to the study of fluctuation and correlation observables of hadronic equilibrium systems. The statistical hadronization model of high energy physics, in its…
Fluctuations and Correlations from Microscopic Transport Theory
V. P. Konchakovski, M. Hauer, M. I. Gorenstein +1
The multiplicity fluctuations in A+A collisions at SPS and RHIC energies are studied within the HSD transport approach. We find a dominant role of the fluctuations in the nucleon p…

Particle number fluctuations and correlations in nucleus-nucleus collisions at SPS and RHIC energies have been studied within the Hadron-String-Dynamics (HSD) transport approach. E…
Statistical Ensembles With Finite Bath: A Description for an Event Generator
M. Hauer, S. Wheaton
A Monte Carlo event generator has been developed assuming thermal production of hadrons. The system under consideration is sampled grand canonically in the Boltzmann approximation.…
