Longitudinal Flow Correlations in Xe-Xe Collisions at √sNN = 5.44 TeV with the ALICE Detector
Abstract
Anisotropic flow in relativistic heavy-ion collisions has been studied as a signature of the quark gluon plasma (QGP). For different colliding systems, anisotropic flow has been described by the decomposition of azimuthal correlations into Fourier coefficients, vn. More precisely, the second and third harmonics, v2 and v3, describe the eccentricity of the initial state and the response to the medium. In 2017, Xe-Xe collisions took place in the LHC at √sNN = 5.44 TeV. The v2 and v3 coefficients agreed with the expected behavior of the denser medium compared to others, e.g. Pb-Pb (arXiv:1805.01832v1). Furthermore, it has been seen that longitudinal correlations also show anisotropies in the medium which may be used to constrain the medium properties previously mentioned. These longitudinal correlations can be analyzed and described by Legendre Polynomials. For the Xe-Xe collisions data set recorded by ALICE in 2017, results from longitudinal correlations coefficients, an, are presented.
