Anisotropic flow in Xe–Xe collisions at sNN=5.44 TeV

Collective Effects in Nuclear Collisions: Experimental Overview

“…A clear ordering of v 2 > v 3 > ... > v 7 is observed. This characteristic flow feature is also confirmed by other collaborations [28,30]. At the time of Quark Matter 2018 conference, however, no direct data and theory comparison are available for v n (p T ) in Xe-Xe collisions.…”

“…The new data from LHC Xe-Xe run completed in 2017 provide a new opportunity to constrain η/s further. The first anisotropic flow measurements with 2-and multi-particle cumulant methods in Xe-Xe collisions at √ s NN = 5.02 GeV are reported by ALICE in [28].…”

“…One step further has been done by looking at the differential measurements of v n . The p T -differential measurement have been presented by the ALICE, ATLAS and CMS collaborations [28][29][30]. For example, the ATLAS collaboration has shown measurements of v n (p T ) for n = 2-7 [29].…”

Elliptic flow fluctuations in central collisions of spherical and deformed nuclei

“…In central collisions, where linear hydrodynamic response is exhibited at its best [9,10], an important source of fluctuations that contributes to ε 2 is given by the random orientation of the colliding nuclei, if they are nonspherical. This explains the large magnitude of the rms elliptic flow measured in central collisions of nuclei that have a pronounced deformation, i.e., U+U collisions at the BNL Relativistic Heavy Ion Collider (RHIC) [11], and Xe+Xe collisions at the CERN Large Hadron Collider (LHC) [12]. In the current modeling of initial conditions for hydrodynamics, the non-spherical shape of the nuclei is obtained by adding a quadrupole deformation in the wavefunctions of the colliding bodies, the implementation of which is performed with the guidance of tabulated data on nuclear ground-state deformations [13,14].…”

Measurements of Fourier Harmonics of Azimuthal Anisotropy in Pb+Pb and Xe+Xe Collisions

“…Corresponding results from the ALICE and CMS experiments can be found in Refs. [5][6][7][8]. The Xe ion is almost twice smaller than the Pb ion, which introduces larger initial spatial * Presented at XIII Workshop on Particle Correlations and Femtoscopy (1) arXiv:1809.10648v2 [nucl-ex] 20 Mar 2019 fluctuations of the collision zone in the smaller system.…”
