Detail description
The first longitudinal coefficient a1 as a function of <dNch/deta> in Xe-Xe collisions at √sNN = 5.44 TeV (LHC17n), compared between data and MC HIJING. a1 was computed EbyE using Legendre polynomial decomposition. The values used for <dNch/deta> are published values from ALICE (arXiv:1805.04432). Statistical and systematic uncertainties are included. Systematic errors are averaged along centrality. Systematic errors in Xe-Xe data are assigned from Pb-Pb data systematic errors.
