A systematic study of HBT radii of pions, produced in heavy ion collisions in the intermediate energy regime (SPS), from an integrated (3+1)d Boltzmann+hydrodynamics approach is presented. The calculations in this hybrid approach, incorporating an hydrodynamic stage into the Ultra-relativistic Quantum Molecular Dynamics (UrQMD) transport model, allow for a comparison of different equations of...

The physical scenario for ultrarelativistic heavy-ion collisions is analyzed
where the early dynamics of the system is dominated by the purely transverse
hydrodynamic expansion (transverse hydrodynamics [1,2,3]). The local
isotropization of the system in the momentum space is described in the
schematic way with the help of the Landau matching conditions. The
isotropization process is...

Investigating Dynamics and the EOS with Correlations
Microscopic transport models are found to reproduce well many features
of ultra-relativistic heavy-ion collisions.
Our aim is to study the femtoscopic correlations of different particle
systems: pion-pion, pion-kaon, pion-proton, and pion-Xi within the
quark-gluon string model (QGSM) and ultra-relativistic quantum molecular
dynamics (UrQMD) model.
We are extracting space-time sizes and...

In the last several years it has been revealed that the matter produced in the collisions of the Relativistic Heavy Ion Collider (RHIC) is a nearly perfect fluid, i.e. it can be described with perfect fluid hydrodynamics. There was a long search for exact hydrodynamic models (solutions of the partial differential equations of hydrodynamics) and several models proved to be applicable. There are...

We present the extension of the Buda-Lund hydrodynamic model
from high energy central collisions to peripherial ones. Spectra
and the elliptic flow of indentified particles are described along
with the azimuthal dependence of two-particle correlation function
radii in the ellipsoidally symmetric generalization of the model.
Theoretical predictions were tested against RHIC data. From...

Beyond Gaussians: Extracting Detailed Size and Shape Information

It is argued that the $\mathrm{U_A}(1)$ or chiral symmetry may temporarily be restored in a hot and dense medium that is created in high energy heavy ion collisions. As a consequence, the mass of the $\eta\prime$(958) mesons may be reduced to its quark model value, and the abundancy of the $\eta\prime$ mesons at low $p_T$ may be significantly enhanced.
