Thermodynamics of fireball expansion — •Thorsten Renk1, Roland A. Schneider1, and Wolfram Weise1,2 — 1Technische Universität München — 2ECT∗, Trento
The fireball created in an ultrarelativistic heavy ion collision
is the environment in which all processes providing clues about
the possible formation of the quark-gluon plasma (QGP) happen. It is
therefore
crucial to understand the dynamics of this hot and dense system.
We set up a model in which the fireball evolution is reconstructed
between two stages, the freeze-out, which is accessible by hadronic
observables, and the initial conditions for which the overlap geometry
can be calculated. Using the equation of state (EoS) provided by
a quasiparticle model of the QGP, we are able to calculate
thermodynamical properties in volume slices of constant proper time
and determine the volume expansion self-consistently.
The resulting evolution model can then be tested against other
observables.
