TL;DR
This paper investigates how different QCD-based equations of state influence the azimuthal flow anisotropies and transverse momentum spectra in hydrodynamic models of heavy-ion collisions at LHC energies.
Contribution
It introduces a family of equations of state derived from lattice QCD within a quasiparticle model and applies them to hydrodynamic simulations.
Findings
QCD-based equations of state significantly affect flow anisotropies.
Transverse momentum spectra are sensitive to the choice of equation of state.
Hydrodynamic results help interpret LHC heavy-ion collision data.
Abstract
We present a family of equations of state within a quasiparticle model adjusted to lattice QCD and study the impact on azimuthal flow anisotropies and transverse momentum spectra within hydrodynamic simulations for heavy-ion collisions at energies relevant for LHC.
