Linear and non-linear flow modes of charged and identified particles in Pb-Pb collisions at $\sqrt{s_\mathrm{NN}}$=5.02 TeV with ALICE

The higher order harmonic flow observables ν n ( n > 3) and their non-linear responses to the initial state anisotropy have the strong potential to constrain shear and bulk viscosity to entropy ratios because of different sensitivities for various stages of heavy-ion collisions. The measurements...

Sumario:The higher order harmonic flow observables ν n ( n > 3) and their non-linear responses to the initial state anisotropy have the strong potential to constrain shear and bulk viscosity to entropy ratios because of different sensitivities for various stages of heavy-ion collisions. The measurements of the flow coefficients and the non-linear coefficients up to the ninth and fifth harmonic, respectively, are presented in Pb–Pb collisions at sNN=5.02TeV for charged hadrons. In addition, the results of p T -differential non-linear flow modes for π ± , K ± , p+p¯ , K 0 s , Λ+Λ¯s0 and ϕ are presented. The results are compared to the same measurements at 2.76 TeV and calculations from state of the art hydrodynamic models.
