Freeze-out dynamics at RHIC
نویسنده
چکیده
Investigation of the final hadronic state properties of ultrarelativistics pp and Au+Au collisions supplies information on freeze-out conditions at RHIC and possible insights into early stages of these collisions. A variety of particle spectra measured by STAR are studied within the framework of chemical and local kinetic equlibrium models. Here we present the extracted chemical and final kinetic freeze-out temperatures, strangeness saturation factor, final collective flow velocity, and the inferred flow velocity at chemical freeze-out. In light of those measurements we disscuss dynamical evoution of the collission system.

Strangeness and Qgp Freeze-out Dynamics
We compare chemical and thermal analysis of the SPS Pb–Pb results at 158A GeV, and present a first chemical analysis of RHIC results. We show how a combined analysis of several strange hadron resonances can be used in a study of freeze-out dynamics.
متن کاملObservable implications of geometrical and dynamical aspects of freeze-out in heavy ion collisions
Using an analytical parameterization of hadronic freeze-out in relativistic heavy ion collisions, we present a detailed study of the connections between features of the freeze-out configuration and physical observables. We focus especially on anisotropic freeze-out configurations (expected in general for collisions at finite impact parameter), azimuthally-sensitive HBT interferometry, and final...
متن کاملThermal description of transverse - momentum spectra at RHIC ∗
We present a simple model describing the p⊥-spectra of hadrons measured at RHIC at √ sNN = 130 GeV. Our approach is a combination of the thermal model, used frequently in the studies of the relative hadron yields [1–9], with a model of the hydrodynamic expansion of matter at freeze-out. The main assumptions of the model [10–12] are as follows: i) the chemical freeze-out and the thermal freeze-o...
متن کاملFe b 19 99 Analysis of reaction dynamics at RHIC in a combined parton / hadron transport approach
We introduce a transport approach which combines partonic and hadronic degrees of freedom on an equal footing and discuss the resulting reaction dynamics. The initial parton dynamics is modeled in the framework of the parton cascade model, hadronization is performed via a cluster hadroniza-tion model and configuration space coalescence, and the hadronic phase is described by a microscopic hadro...
متن کاملStatistical Hadronization Phenomenology in Heavy Ion Collisions at Sps and Rhic Energies
This dissertation examines the phenomenology of statistical hadronization at ultrarelativistic energies. We start with an overview of current experimental and theoretical issues in Relativistic heavy ion physics. We then introduce statistical hadronization, and show how it gives a description of particle abundances and spectra through relativistic covariance and entropy maximization. We argue t...
