Anisotropic hydrodynamic modeling of 2.76 TeV Pb-Pb collisions

Understand

We compare phenomenological results from 3+1d quasiparticle anisotropic hydrodynamics (aHydroQP) with experimental data collected in LHC 2.76 TeV Pb-Pb collisions.

• In particular, we present comparisons of particle spectra, average transverse momentum, elliptic flow, and HBT radii.
• The aHydroQP model relies on the introduction of a single temperature-dependent quasiparticle mass which is fit to lattice QCD data.
• By taking moments of the resulting Boltzmann equation, we obtain the dynamical equations used in the hydrodynamic stage which include the effects of both shear and bulk viscosities.
