Spectra, flow and HBT in Pb-Pb collisions at the LHC
Piotr Bozek
TL;DR
This paper uses viscous hydrodynamics to analyze Pb-Pb collision data at the LHC, successfully describing spectra, flow, and interferometry radii with a low shear viscosity, consistent with RHIC conditions.
Contribution
It demonstrates that relativistic viscous hydrodynamics with Glauber initial conditions accurately models LHC Pb-Pb collision observables using a shear viscosity to entropy ratio of 0.08.
Findings
Data can be described with eta/s=0.08
Viscosities and EoS are consistent with RHIC
Hydrodynamics reproduces spectra, flow, and HBT radii
Abstract
The transverse momentum spectra, elliptic flow and interferometry radii for Pb-Pb collisions at the LHC are calculated in relativistic viscous hydrodynamics. For Glauber model initial conditions, we find that the data can be described using a small value of shear viscosity eta/s=0.08. The viscosities and the equation of state are the same as used for RHIC energies.
