Abstract (data abstract)
Transverse momentum $(p_{\rm T})$ spectra of charged particles was measured at mid-pseudorapidity in Xe–Xe collisions at $\sqrt{s_{\rm NN}} = 5.44$ TeV, in the kinematic range of $0.15<p_{\rm T}<50$ GeV/c and $|\eta|<0.8$. The pp reference at $\sqrt{s} = 5.44$ TeV is interpolated between existing pp measurements at $\sqrt{s} = 5.02$ and $7$ TeV. The nuclear modification factor is calculated for Xe-Xe and Pb-Pb collisions at similar center-of-mass energy, as a function of $p_{\rm T}$ and the charged particle multiplicity density. The average transverse momentum $\langle p_{\rm T} \rangle$ is calculated for both systems, as well as the ratio between them.
