The measurements are based on data collected by the CMS experiment at the LHC. The yield of primary charged hadrons produced in xenon-xenon collisions in the pseudorapidity range $|\\eta|$ $<$ 3.2 is determined using the silicon pixel detector in the CMS tracking system. For the 5% most central collisions, the charged-hadron pseudorapidity density in the midrapidity region $|\\eta|$ $<$ 0.5 is found to be 1187 $\\pm$ 36 (syst), with a negligible statistical uncertainty. The rapidity distribution of charged hadrons is also presented in the range $|y|$ $<$ 3.2 and is found to be independent of rapidity around $y =$ 0. Existing Monte-Carlo event generators are unable to simultaneously describe both results. Comparisons of charged-hadron multiplicities between xenon-xenon and lead-lead collisions at similar collision energies show that particle production at midrapidity is strongly dependent on the collision geometry in addition to the system size and collision energy.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.88285.v1/t1","@type":"Dataset","description":"Averaged and symmetrised charged-hadron pseudorapidity density distributions in XeXe collisions at $\\sqrt{s_{NN}} = 5.44$ TeV, for events in the 0--80\\%,...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.88285.v1/t2","@type":"Dataset","description":"Averaged and symmetrised charged-hadron rapidity density distributions in XeXe collisions at $\\sqrt{s_{NN}} = 5.44$ TeV, for events in the 0--80\\%...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.88285.v1/t3","@type":"Dataset","description":"Charged-hadron pseudorapidity density in XeXe collisions at $\\sqrt{s_{NN}} = 5.44$ TeV at midrapidity as a function of event centrality.
