Measurement of anisotropic flow in XeXe collisions at 5.44 TeV with the CMS experiment

New measurements of anisotropic flow in XeXe collisions at a center-of-mass energy of 5.44 TeV per nucleon pair,collected by the CMS experiment at the LHC, are presented. The $v_2$, $v_3$ and $v_4$ Fourier coefficients of the anisotropicazimuthal distribution are obtained employing three different analysis techniques: two-particle correlations, the scalarproduct method, and multiparticle cumulants, which have different sensitivities to non-flow and flow fluctuation effects.The results are shown as a function of transverse momentum ($p_T$) for various centrality selections, and compared withcorresponding results from PbPb collisions. These new measurements in a smaller nucleus-nucleus system than PbPbprovide additional insights into the system-size dependence of the collective flow induced by the dominant collision ge-ometry and its fluctuations. In particular, these results, compared to theoretical predictions and Monte Carlo generators,will provide important details on the system size dependence of the medium response in heavy ion collisions. They alsooffer a unique opportunity to study the onset of flow from small to large systems.
