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 v2, v3 and v4 Fourier coefficients of the anisotropic azimuthal distribution are obtained employing three different analys...

| Summary: | 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 v2, v3 and v4 Fourier coefficients of the anisotropic
azimuthal distribution are obtained employing three different analysis techniques: two-particle correlations, the scalar
product 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 (pT ) for various centrality selections, and compared with
corresponding results from PbPb collisions. These new measurements in a smaller nucleus-nucleus system than PbPb
provide additional insights into the system-size dependence of the collective flow induced by the dominant collision geometry 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 also
offer a unique opportunity to study the onset of flow from small to large systems. |
