Abstract: are measured using xenon-xenon (XeXe) collisions at √sNN = 5.44TeV. The data, corresponding to an integrated luminosity of 3.42µb−1, were collected in 2017 by the CMS experiment at the LHC. The yields are reported as functions of collision centrality and transverse momentum, pT, from 0.5 to 100GeV. A previously reported pT spectrum from proton-proton collisions at √s = 5.02TeV is used for comparison after correcting for the difference in center-of-mass energy. The nuclear modification factors using this reference, R∗AA, are constructed and compared to previous measurements and theoretical predictions. In head-on collisions, the R∗AA has a value of 0.17 in the pT range of 6–8GeV, but increases to approximately 0.7 at 100GeV. Above ≈6GeV, the XeXe data show a notably smaller suppression than previous results for lead-lead (PbPb) collisions at √sNN = 5.02TeV when compared at the same centrality (i.e., the same fraction of total cross section). However, the XeXe suppression is slightly greater than that for PbPb in events having a similar number of participating nucleons.
