- Аннотация: This paper describes the measurements of flow harmonics v2–v6 in 3 μb−1 of Xe + Xe collisions at √s_NN = 5.44 TeV performed using the ATLAS detector at the Large Hadron Collider (LHC). Measurements of the centrality, multiplicity, and pT dependence of the vn obtained using two-particle correlations and the scalar product technique are presented. The measurements are also performed using a template-fit procedure, which was developed to remove nonflow correlations in small collision systems. This nonflow removal is shown to have a significant influence on the measured vn at high pT, especially in peripheral events. Comparisons of the measured vn with measurements in Pb + Pb collisions and p + Pb collisions at √s_NN = 5.02 TeV are also presented. The vn values in Xe + Xe collisions are observed to be larger than those in Pb + Pb collisions for n = 2, 3, and 4 in the most central events. However, with decreasing centrality or increasing harmonic order n,the vn values in Xe + Xe collisions become smaller than those in Pb + Pb collisions. The vn in Xe + Xe andPb + Pb collisions are also compared as a function of the mean number of participating nucleons, <Npart>, and the measured charged-particle multiplicity in the detector. The v3 values in Xe + Xe and Pb + Pb collisions are observed to be similar at the same Npart or multiplicity, but the other harmonics are significantly different. The ratios of the measured vn in Xe + Xe and Pb + Pb collisions, as a function of centrality, are also compared to theoretical calculations.
