6. Determination of Quark-Gluon-Plasma properties via Bayesian analysis

Prof. Steffen Bass (Duke University)

03/09/2018, 09:30

Week 2

A primary goal of heavy-ion physics is the measurement of the fundamental properties of the quark-gluon plasma (QGP), notably its transport coefficients and initial state properties. Since these properties are not directly measurable, one relies on a comparison of experimental data to computational models of the time-evolution of the collision to connect measured observables to the properties...

35. Polarization in relativistic fluids

Francesco Becattini (University of Florence (IT))

03/09/2018, 11:15

Week 2

The observation of a finite global polarization in agreement with
theoretical predictions has opened a new dimension in relativistic
heavy ion physics as well as in relativistic hydrodynamics, with
several intriguing connections to chiral and electromagnetic effects.
Very recent experimental observations seem to challenge the
hydrodynamic predictions. In this talk, the status of the theory...

10. One particle distribution function and shear viscosity in magnetic field: a relaxation time approach

Dr Victor Roy (NISER, India)

03/09/2018, 14:30

Week 2

We calculate the $\delta f$ correction to the one particle distribution function in
presence of magnetic field and non-zero shear viscosity within the relaxation time approximation. The $\delta f$ correction is found to be electric charge dependent. Subsequently, we also calculate one longitudinal and four transverse shear viscous coefficients as a function of dimensionless Hall parameter...

22. Elliptic flow with polarized beams

Week 2

We discuss https://arxiv.org/abs/1808.09840

19. Ultracentral heavy-ion collisions as a probe of nuclear structure

Prof. Jacquelyn Noronha-Hostler (Rutgers University)

04/09/2018, 11:15

Week 2

In recent years heavy-ion collisions have noted that a preference for both a deformed proton and deformed nuclei are seen in comparing flow observables to relativistic viscous hydrodynamic calculations. Thus far, all deformations of nuclei have only considered the ground state of the nucleus. In the case of XeXe collisions, it was found that the deformed Xenon nucleus increase elliptical flow...

30. Collectivity of heavy flavor quarks in small collisions system

Zhenyu Chen

05/09/2018, 09:30

Week 2

Recent years, evidence for collective effects has been revealed in small collision systems when looking at events releasing large number of particles. The experimental observations lead to a debate of the formation of strongly coupled Quark-Gluon Plasma in those small collision systems. Azimuthal anisotropy coefficient (vn) of heavy-flavor quarks can shed light on their coupling strength to...

27. Fluctuatioans and long time tails in fluid dynamics

Thomas Schaefer

05/09/2018, 11:30

Week 2

We study the role of fluctuations in relativistic fluid dynamics. We consider two issues, long-time tails in current-current correlation functions, and simulations of baryon diffusion in the vicinity of a critical point.

39. Some results and challenges for hydro modelling at RHIC BES

Iurii Karpenko (SUBATECH Nantes)

Week 2

In this talk I overview the results of our studies of heavy ion collisions at RHIC BES energies in the framework of a viscous hydro + cascade model, vHLLE+UrQMD, focusing on the following phenomena:

• Lambda polarization - from RHIC BES to LHC energies
• Femtoscopic observables at RHIC BES

And discuss challenges for hydrodynamic modelling at the lower collision energies (RHIC BES, FAIR,...
