Comparison of results from a 2+1D relativistic viscous hydrodynamic model to elliptic and hexadecapole flow of charged hadrons measured in Au-Au collisions at $\sqrt{s_{\rm {NN}}}$ = 200 GeV

Understand

Simulated results from a 2+1D relativistic viscous hydrodynamic model have been compared to the experimental data on the centrality dependence of invariant yield, elliptic flow ($v_{2}$), and hexadecapole flow ($v_{4}$) as a function of transverse momentum ($p_{T}$) of charged hadrons in Au-Au collisions at $\sqrt{s_{\rm {NN}}}$ = 200 GeV.

• Results from two types of initial transverse energy density profile, one based on the Glauber model and other based on Color-Glass-Condensate (CGC) are presented.
• We observe no difference in the simulated results on the invariant yield of charged hadrons for the calculations with different initial conditions.
• The comparison to the experimental data on invariant yield of charged hadrons supports a shear viscosity to entropy density ratio ($\eta/s$) between 0 to 0.12 for the 0-10% to 40-50% collision centralities.
