Anisotropic flow of identified particles in Pb--Pb collisions at $\sqrt{s_{\mathrm{N}\mathrm{N}}}=5.02$ TeV

Anisotropic flow is sensitive to the shear $(\eta \mathrm{/}s)$ and bulk ($\zeta \mathrm{/}s$) viscosity of the quark-gluon plasma created in heavy-ion collisions, as well as the initial state of such collisions and hadronization mechanisms. In these proceedings, elliptic ($v_2$) and higher harmonic ($v_3,v_4$) flow coefficients of ${\pi }^{\pm }$, $K^{\pm }$, p$(\bar{\mathrm{p}})$ and the $\varphi$-meson, are presented for Pb-Pb collisions at the highest-ever center-of-mass energy of $\sqrt{s_{\mathrm{N}\mathrm{N}}}$ = 5.02 TeV. Comparisons to hydrodynamic calculations (IP-Glasma, MUSIC, UrQMD) are shown to constrain the initial conditions and viscosity of the medium.
