Effect of temperature-dependent eta/s on flow anisotropies
Harri Niemi, Gabriel S. Denicol, Pasi Huovinen +2
We investigate the effects of a temperature-dependent shear viscosity over entropy density ratio eta/s on the flow anisotropy coefficients v_2 and v_4 in ultrarelativistic heavy-io…
Hydrodynamics of a quark droplet
Johan J. Bjerrum-Bohr, Igor N. Mishustin, Thomas Døssing
We present a simple model of a multi-quark droplet evolution based on the hydrodynamical description. This model includes collective expansion of the droplet, effects of the vacuum…
The QCD Phase Diagram in Chiral Fluid Dynamics
Marlene Nahrgang, Marcus Bleicher
We give a general overview about the approaches to study the phase diagram of QCD. Thereafter, we examine the evolution of a fireball in a chiral fluid dynamic model including none…
Analysis of dilepton production in Au+Au collisions at sqrt(s_NN)=200 GeV within the Parton-Hadron-String Dynamics (PHSD) transport approach
O. Linnyk, W. Cassing, J. Manninen +2
We address dilepton production in Au+Au collisions at sqrt(s_NN)=200 GeV by employing the parton-hadron-string dynamics (PHSD) off-shell transport approach. Within the PHSD one goe…
The phase diagram in space
Giorgio Torrieri, Stefano Lottini, Igor Mishustin +1
We examine the phase diagram of hadronic matter when the number of colors, as well as temperature and density, are varied. We show that in this regime several new phase transitions…
Microscopic Composition of Ion-Ion Interaction Potentials
A. S. Umar, V. E. Oberacker, J. A. Maruhn +1
We present a new method to calculate the total ion-ion interaction potential in terms of building blocks which we refer to as "single-particle interaction potentials". This allows…
Dense Matter and Neutron Stars in Parity Doublet Models
S. Schramm, V. Dexheimer, R. Negreiros +1
We investigate the properties of dense matter and neutron stars. In particular we discuss model calculations based on the parity doublet picture of hadronic chiral symmetry. In thi…
Non-exponential decay in quantum field theory and in quantum mechanics: the case of two (or more) decay channels
Francesco Giacosa
We study the deviations from the exponential decay law, both in quantum field theory (QFT) and quantum mechanics (QM), for an unstable particle which can decay in (at least) two de…
The O(2) model in polar coordinates at nonzero temperature
Mara Grahl, Elina Seel, Francesco Giacosa +1
We study the restoration of spontaneously broken symmetry at nonzero temperature in the framework of the O(2) model using polar coordinates. We apply the CJT formalism to calculate…
Dynamics of nuclear single-particle structure in covariant theory of particle-vibration coupling: from light to superheavy nuclei
E. V. Litvinova, A. V. Afanasjev
The impact of particle-vibration coupling and polarization effects due to deformation and time-odd mean fields on single-particle spectra is studied systematically in doubly magic…
Rise of azimuthal anisotropies as a signature of the Quark-Gluon-Plasma in relativistic heavy-ion collisions
V. P. Konchakovski, E. L. Bratkovskaya, W. Cassing +2
The azimuthal anisotropies of the collective transverse flow of hadrons are investigated in a large range of heavy-ion collision energy within the Parton-Hadron-String Dynamics (PH…
Fluid dynamical equations and transport coefficients of relativistic gases with non-extensive statistics
T. S. Biro, E. Molnar
We derive equations for fluid dynamics from a non-extensive Boltzmann transport equation consistent with Tsallis' non-extensive entropy formula. We evaluate transport coefficients…
Determination of the Shear Viscosity Relaxation Time at Weak and Strong Coupling
G. S. Denicol, J. Noronha, H. Niemi +1
We investigate the microscopic origin of the relaxation time coefficient in relativistic fluid dynamics. We show that the extraction of the shear viscosity relaxation time via the…
Quark Polarization in a Viscous Quark-Gluon Plasma
Xu-Guang Huang, Pasi Huovinen, Xin-Nian Wang
Quarks produced in the early stage of non-central heavy-ion collisions could develop a global spin polarization along the opposite direction of the reaction plane due to the spin-o…
Energy dependent growth of the nucleon and hydrodynamic initial conditions
Ulrich W. Heinz, J. Scott Moreland
Due to gluon saturation, the growth of the inelastic nucleon-nucleon cross section with increasing collision energy sqrt(s) results in a broadening of the nucleon's density distrib…
Fluctuation Probes of Early-Time Correlations in Nuclear Collisions
Sean Gavin, George Moschelli
Correlation measurements imply that anisotropic flow in nuclear collisions includes a novel triangular component along with the more familiar elliptic-flow contribution. Triangular…
The low energy frontier: What is exciting about physics below the top RHIC energy
Marcus Bleicher
These proceedings summarize my plenary talk at Quark Matter 2011 with a focus on the future perspectives of the low energy programs at RHIC, FAIR, NICA and CERN.

O. Linnyk, E. L. Bratkovskaya, V. Ozvenchuk +2
Dilepton production in In+In collisions at 158 AGeV is studied within the microscopic parton-hadron-string dynamics (PHSD) transport approach that incorporates explicit partonic de…
The Quest for the Heaviest Uranium Isotope
S. Schramm, D. Gridnev, D. V. Tarasov +2
We study Uranium isotopes and surrounding elements at very large neutron number excess. Relativistic mean field and Skyrme-type approaches with different parametrizations are used…
The QGP shear viscosity -- elusive goal or just around the corner?
Chun Shen, Steffen A Bass, Tetsufumi Hirano +4
With the new viscous hydrodynamic + hadron cascade hybrid code VISHNU, a rather precise (O(25%)) extraction of the QGP shear viscosity (eta/s)_QGP from heavy-ion elliptic flow data…
The thermal model on the verge of the ultimate test: particle production in Pb-Pb collisions at the LHC
A. Andronic, P. Braun-Munzinger, K. Redlich +1
We investigate the production of hadrons in nuclear collisions within the framework of the thermal (or statistical hadronization) model. We discuss both the ligh-quark hadrons as w…
