Dr Yoshimasa Hidaka (RIKEN Nishina Center)17/08/2012, 14:00Oral PresentationWe discuss the phase diagram of quantum chromodynamics (QCD) at finite T and finite quark chemical potential \mu. In particular, we focus on the QCD critical point(s), which has attracted considerable attention in its search at the relativistic heavy ion collision experiments. However, not only the location, but even the existence has not yet been settled. In this talk, we show that the...Go to contribution page

Rajiv V Gavai (Tata Institute, Mumbai, India)17/08/2012, 14:20Exploring the QCD phase diagramOral PresentationWe simulate QCD with two light dynamical quarks on a 32^3 X 8 lattice by tuning the current quark mass such that the Goldstone pion mass is about 230 MeV. Earlier results of our Mumbai group corresponded to the same physical parameters but were on coarser lattices at respectively 1.33 times and twice the lattice cut-off (a) compared to these simulations, thus permitting us a march towards...Go to contribution page

Joseph Kapusta (University of Minnesota (US))17/08/2012, 14:40Exploring the QCD phase diagramOral PresentationHydrodynamic fluctuations are inherent in any small space-time varying system. They may be significantly impacted by the presence of a critical point in the QCD equation of state during the expansion phase of a heavy ion collision. Simple models are studied to gain insight into the essential physics. This study suggests which observables are most sensitive to a critical point, although much...Go to contribution page

SABITA DAS (I)17/08/2012, 15:00Oral PresentationThe RHIC Beam Energy Scan (BES) program aims to study the QCD phase diagram. The main focus is to search for signals of the hypothesized critical point and the onset of the quark-hadron phase transition. The BES program covers a large part of the QCD phase diagram ($T$ vs.$mu_{B}$). With its uniform acceptance and excellent particle identification, STAR has collected large event samples in the...Go to contribution page

Shusu Shi (CCNU)17/08/2012, 15:20Exploring the QCD phase diagramOral PresentationThe exploration of the QCD phase diagram in the region of a possible phase transition between the Quark Gluon Plasma (QGP) and the hadron gas phase is one of the main goals of the RHIC Beam Energy Scan(BES). One of the most important observables from high-energy nuclear collisions to study the early evolution of the expanding system is the elliptic flow $v_{2}$. At the top RHIC energy,...Go to contribution page

Dr Marlene Nahrgang17/08/2012, 15:40Exploring the QCD phase diagramOral PresentationStrong fluctuations in observables are believed to provide decisive signals for identifying phase transitions of QCD in relativistic heavy-ion collisions. To study this possibility under realistic conditions of the expansion and the cooling of the fireball we performed dynamic simulations within our approach of nonequilibrium chiral fluid dynamics. Based on an effective phase transition model,...Go to contribution page
