25. The QCD phase transition in a fully dynamical model of heavy-ion collisions

Christoph Herold (Frankfurt Institute for Advanced Studies)

Experimental signals for a possible QCD critial point and first-order phase transition are strongly influenced by the rapid nonequilibrium dynamics during a heavy-ion collision. In order to estimate and understand these effects we study the cooling through the phase transition within a nonequilibrium chiral fluid dynamics model. The order parameters for the chiral and deconfinement transition...

85. Study of freeze-out dynamics in STAR at RHIC beam energy scan program

The STAR experiment at RHIC has collected data at various collision energies in its beam energy scan (BES) program to study the QCD phase diagram. The BES program covers a large part of the QCD phase diagram in terms of temperature (T) versus baryon chemical potential ($\mu_B$). The collected data set can be used to study the kinetic and chemical freeze-out dynamics. The kinetic and...

87. Beam energy scan using a viscous hydro+cascade model

Talk

We employ the up-to-date version of viscous Hydro-Kinetic Model (vHKM) based on 3+1D viscous hydrodynamic code coupled to UrQMD hadron cascade. Following the experimental program at BNL RHIC, we perform a similar "energy scan" in the model, and study the collision energy dependence of charged and identified hadron spectra, flow coefficients and femtoscopic radii. For this aim the equation of...

23. The elliptic flow and the shear viscosity of the QGP within a kinetic approach

Dr SALVATORE PLUMARI (UNIVERSITY OF CATANIA, ITALY)

Talk

We investigate within a parton cascade approach at fixed $\eta/s$ ratio the effect of a temperature dependent $\eta/s(T)$ at three different beam energies from RHIC for Au+Au at $\sqrt(s)=$62.4, 200 GeV to LHC energies for Pb+Pb at $\sqrt(s)=$2.76 TeV. An important result is that for the different beam energies considered the suppression of the elliptic flow due to the viscosity of the...

11. Higher moments of net kaon multiplicity distributions at RHIC energies for the search of QCD Critical Point

Mr Amal( for the STAR collaboration) Sarkar (Indian Institute of Technology Bombay, Mumbai)

Talk

The Relativistic Heavy-Ion Collider (RHIC), at BNL, has started its beam energy scan(BES) program by colliding heavy-ions covering a wide range in baryonic chemical po- tential. One of the main goals of this beam energy scan program is to locate the critical point which is postulated to lie at the end of the phase transition boundary between partonic and hadronic matter. Finite temperature...

42. Probing the QCD phase diagram with the measurements of $\phi$-meson production and elliptic flow in the heavy-ion collision at STAR.

Talk

The main goal of the Beam Energy Scan (BES) program at Relativistic Heavy Ion Collider (RHIC) is to study the QCD phase diagram by varying the colliding beam energy. Due to the small hadronic interaction cross-section, the yield and elliptic flow of the $\phi$ meson are primarily controlled by the partonic interaction in the relativistic heavy-ion collisions[1,2]. Therefore, the $\phi$ meson...
