Transverse momentum (pT) spectra of charged particles at mid-pseudorapidity in Xe–Xe collisions at √sNN = 5.44 TeV measured with the ALICE apparatus at the Large Hadron Collider are reported. The kinematic range 0.15 < pT < 50 GeV/c and |η| < 0.8 is covered. Results are presented in nine classes of collision centrality in the 0–80% range. For comparison, a pp reference at the collision energy of √s = 5.44 TeV is obtained by interpolating between existing pp measurements at √s = 5.02 and 7 TeV. The nuclear modification factors in central Xe–Xe collisions and Pb–Pb collisions at a similar center-of- mass energy of √sNN = 5.02 TeV, and in addition at 2.76 TeV, at analogous ranges of charged particle multiplicity density ⟨dNch/dη⟩ show a remarkable similarity at pT > 10 GeV/c. The centrality dependence of the ratio of the average transverse momentum ⟨pT⟩ in Xe–Xe collisions over Pb–Pb collision at s = 5.02 TeV is compared to hydrodynamical model calculations.

Özet (dc.description.abstract) | Transverse momentum (pT) spectra of charged particles at mid-pseudorapidity in Xe–Xe collisions at √sNN = 5.44 TeV measured with the ALICE apparatus at the Large Hadron Collider are reported. The kinematic range 0.15 < pT < 50 GeV/c and |η| < 0.8 is covered. Results are presented in nine classes of collision centrality in the 0–80% range. For comparison, a pp reference at the collision energy of √s = 5.44 TeV is obtained by interpolating between existing pp measurements at √s = 5.02 and 7 TeV. The nuclear modification factors in central Xe–Xe collisions and Pb–Pb collisions at a similar center-of- mass energy of √sNN = 5.02 TeV, and in addition at 2.76 TeV, at analogous ranges of charged particle multiplicity density ⟨dNch/dη⟩ show a remarkable similarity at pT > 10 GeV/c.
