Multiplicity Fluctuations and Correlations in Limited Momentum Space Bins in Relativistic Gases
Michael Hauer, Giorgio Torrieri, Spencer Wheaton
Multiplicity fluctuations and correlations are calculated within thermalized relativistic ideal quantum gases. These are shown to be sensitive to the choice of statistical ensemble…
Generalized Entropy and Transport Coefficients of Hadronic Matter
Azwinndini Muronga
We use the generalized entropy four-current of the Muller-Israel-Stewart (MIS) theory of relativistic dissipative fluids to obtain information about fluctuations around equilibrium…
Multiplicity Distributions in Canonical and Microcanonical Statistical Ensembles
M. Hauer, V. V. Begun, M. I. Gorenstein
The aim of this paper is to introduce a new technique for calculation of observables, in particular multiplicity distributions, in various statistical ensembles at finite volume. T…
Particle number fluctuations in nuclear collisions within excluded volume hadron gas model
M. I. Gorenstein, M. Hauer, D. O. Nikolajenko
The multiplicity fluctuations are studied in the van der Waals excluded volume hadron-resonance gas model. The calculations are done in the grand canonical ensemble within the Bolt…
Transition from Baryon- to Meson-Dominated Freeze Out -- Early Decoupling around 30 A GeV?
H. Oeschler, J. Cleymans, K. Redlich +1
The recently discovered sharp peak in the excitation function of the K+/pi+ ratio around 30 A GeV in relativistic heavy-ion collisions is discussed in the framework of the Statisti…
Entropy in the Thermal Model
Maciej Andrzej Stankiewicz
A brief review of the Hadron Gas model with reference to high energy heavy ion collisions is presented. The entropy dependence on temperature and baryonic chemical potential is num…
