(2018). Charged-particle nuclear modification factors in XeXe collisions at √sNN=5.44 TeV. Journal of High Energy Physics, 2018 (10), 10.1007/JHEP10(2018)138en_US
dc.description.abstract© 2018, The Author(s). The differential yields of charged particles having pseudorapidity within |η| < 1 are measured using xenon-xenon (XeXe) collisions at sNN=5.44 TeV. The data, corresponding to an integrated luminosity of 3.42 μb−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 100 GeV. A previously reported pT spectrum from proton-proton collisions at s=5.02 TeV is used for comparison after correcting for the difference in center-of-mass energy. The nuclear modification factors using this reference, RAA*, are constructed and compared to previous measurements and theoretical predictions. In head-on collisions, the RAA* has a value of 0.17 in the pT range of 6–8 GeV, but increases to approximately 0.7 at 100 GeV. Above ≈6 GeV, the XeXe data show a notably smaller suppression than previous results for lead-lead (PbPb) collisions at sNN=5.02 TeV 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.en_US
