6 seminars, 20 min. each
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...
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...
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...
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...
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....
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...
