A Non-Extensive Model for Quark Matter Produced in Heavy Ion Collisions
T. S. Biro, G. Purcsel
We describe quark matter in the framework of non-extensive thermodynamics. We point out that partcile spectra with power-law tail lead to an increased energy and entropy per partic…
How low is the thermodynamical limit?
Tamas S. Biro, Gabor Purcsel, Berndt Muller
We analyze how can some dynamical process lead to (almost) exponential distribution of hadrons without instantaneous equipartition with a heat bath. We present a model for parton d…
Canonical enhancement as a result of Poisson distribution
T. S. Biro
We point out that a certain finite size effect in heavy ion physics, the canonical enhancement, is based on the difference of conservation constrained pair statistics for Poisson a…
Hyperon ratios at RHIC and the coalescence predictions at mid-rapidity
J. Zimanyi, P. Levai, T. Csorgo +1
Quark coalescence predictions for various multi-strange baryon to anti-baryon ratios for central Au+Au collisions at RHIC energies are compared to preliminary data of the STAR coll…
Hadronization in the Chromodielectric Model
G. Martens, C. Traxler, U. Mosel +1
We study the dynamics of quarks and gluons in the Chromodielectric Model (CDM), which contains a dynamical description of confinement. Results are presented for hadronization out o…
Stochastic Disoriented Chiral Condensates
C. Greiner, Z. Xu, T. S. Biro
Applying a Langevin description of the linear sigma model we investigate four different scenarios for the evolution of a disoriented chiral condensate: annealing or quench with ini…
