70. Holographic collisions in non-conformal theories

maximilian attems (University of Barcelona)

19/09/2017, 17:00

We use the gauge/gravity duality to model the out-of-equilibrium first stage of
a heavy ion collision through the collision of gravitational shockwaves in
numerical relativity. This investigation of collisions of sheets of energy
density in a non-conformal theory with a gravity dual is the first non-conformal
holographic simulation of a heavy ion collision. I will discuss the new physics
that...

91. Quasiparticle second-order viscous hydrodynamics from an effective Boltzmann equation

Radoslaw Ryblewski (Institute of Nuclear Physics PAN)

19/09/2017, 17:20

We present the derivation of second-order relativistic viscous hydrodynamics from an effective Boltzmann equation for a system consisting of quasiparticles of a single species. We consider temperature-dependent masses of the quasiparticles and devise a thermodynamically-consistent framework to formulate second-order evolution equations for shear and bulk viscous pressure corrections. The main...

45. Forward-backward correlations in Pb–Pb collisions at 2.76 and 5.02 TeV with ALICE

Igor Altsybeev (St Petersburg State University (RU)), ALICE Collaboration

19/09/2017, 17:40

The analysis of forward-backward (FB) multiplicity and event-averaged transverse momentum correlations between particles produced in the forward $(\eta>0)$ and backward $(\eta<0)$ hemispheres of the nucleus-nucleus interaction brings new information, important in the context of our understanding the early dynamics of ultra-relativistic heavy ion collisions.

In this talk, we present new data...

56. Measurement of long-range correlations in pp collisions characterized by presence of a Z-boson

Alexander Milov (Weizmann Institute of Science (IL))

19/09/2017, 18:00

Recent measurements of correlations between two particles separated in pesudorapidity and azimuthal angles have shown striking similarities between results obtained in pp, and in p+A and A+A collision systems. In pp collision system, unlike in the p+A and A+A systems, the strength of the correlations quantified by the anisotropy parameter v_2 does not show any dependence on the...

49. Longitudinal multiplicity fluctuations and flow decorrelations in Pb+Pb collisions with the ATLAS detector

Dominik Karol Derendarz (Polish Academy of Sciences (PL)), ATLAS Collaboration

19/09/2017, 18:20

Longitudinal dynamics has recently become a topic of great interest in the study of ultra-relativistic heavy ion collisions. Both the multiplicity and the azimuthal anisotropic particle distribution measured in narrow $\eta$ intervals can fluctuate from the backward to forward pseudorapidtity region event-by-event. The multiplicity fluctuation is measured in $pp$, $p$+Pb and Pb+Pb collisions....

14. Measurements of longitudinal flow decorrelation in Au+Au Collisions at $\sqrt{s_{NN}}$ = 200 GeV from the STAR Collaboration

Mr Maowu Nie (Shanghai Institute of Applied Physics (SINAP))

19/09/2017, 18:40

Measurement of the longitudinal decorrelation of the harmonic flow event plane can improve our understanding of the longitudinal fluctuation of the QGP at the initial state, and provide important constraints for (3+1)D hydrodynamical models. Recent calculations indicate a stronger longitudinal decorrelation at RHIC energies than at the LHC. In this presentation, we will report the...
