Measurements of Anisotropic Flow in Xe–Xe Collisions at √s_NN = 5.44 TeV Using the ALICE Detector^†

These proceedings summarise the first measurements of anisotropic flow coefficients $v_{\mathrm{n}}$ , $2\le \mathrm{n}\le 4$ , for inclusive charged particles at mid-rapidity in Xe–Xe collisions at $\sqrt{s_{\mathrm{NN}}}=5.44\mathrm{TeV}$ . The results are compared with those from Pb–Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02\mathrm{TeV}$ , in order to test the initial state (IS) models and transport properties. The resulting differences in $v_2$ and $v_3$ between the two systems are consistent with two different hydrodynamical models. Moreover, it is expected that the ratios between $v_{\mathrm{n}}$ and their corresponding eccentricities for $\mathrm{n}=2,3$ scale with transverse density. This is observed for some IS models, except for some deviations in central collisions. These results assist in constraining the initial state as well as the hydrodynamical propagation of the system.
