Charged-hadron production in pp, p+Pb, Pb+Pb, and Xe+Xe collisions at p sNN = 5 TeV with the ATLAS detector at the LHC

Popis výsledku v původním jazyce

This paper presents measurements of charged-hadron spectra obtained in pp,p+Pb, and Pb+Pb collisions at ps or psNN = 5.02TeV, and in Xe+Xe collisions atpsNN = 5.44TeV. The data recorded by the ATLAS detector at the LHC have total integratedluminosities of 25 pb-1, 28 nb-1, 0.50 nb-1, and 3 μb-1, respectively. The nuclearmodification factors RpPb and RAA are obtained by comparing the spectra in heavy-ion andpp collisions in a wide range of charged-particle transverse momenta and pseudorapidity.The nuclear modification factor RpPb shows a moderate enhancement above unity witha maximum at pT 3 GeV; the enhancement is stronger in the Pb-going direction. Thenuclear modification factors in both Pb+Pb and Xe+Xe collisions feature a significant,centrality-dependent suppression. They show a similar distinct pT-dependence with a localmaximum at pT 2 GeV and a local minimum at pT 7 GeV. This dependence is moredistinguishable in more central collisions. No significant ||-dependence is found. A comprehensivecomparison with several theoretical predictions is also provided. They typicallydescribe RAA better in central collisions and in the pT range from about 10 to 100 GeV.
