Measurements of Fourier harmonics of azimuthal anisotropy in Pb+Pb and Xe+Xe collisions

Abstract

The high-statistics data sets collected by the LHC experiments during the heavy-ion runs allow for a detailed study of the azimuthal anisotropy of charged particles. This report presents the selected results of $v_n$ measured in Pb+Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV and Xe+Xe collisions at $\sqrt{s_{\mathrm{NN}}}=5.44$ TeV, with emphasis on the higher order Fourier coefficients, $v_n$, sensitive to initial state fluctuations of the medium created in ultra-relativistic heavy-ion collisions.
