Pseudorapidity distributions of charged hadrons in xenon-xenon collisions at root S-NN=5.44 TeV
Measurements of the pseudorapidity distributions of charged hadrons produced in xenon-xenon collisions at a nucleon-nucleon centre-of-mass energy of √sNN = 5.44 TeV are presented. The measurements are based on data collected by the CMS experiment at the LHC. The yield of primary charged hadrons p...

| description | Measurements of the pseudorapidity distributions of charged hadrons produced in xenon-xenon collisions
at a nucleon-nucleon centre-of-mass energy of √sNN = 5.44 TeV are presented. The measurements are
based on data collected by the CMS experiment at the LHC. The yield of primary charged hadrons
produced in xenon-xenon collisions in the pseudorapidity range |η| < 3.2 is determined using the
silicon pixel detector in the CMS tracking system. For the 5% most central collisions, the chargedhadron pseudorapidity density in the midrapidity region |η| < 0.5 is found to be 1187 ± 36 (syst),
with a negligible statistical uncertainty. The rapidity distribution of charged hadrons is also presented
in the range |y| < 3.2 and is found to be independent of rapidity around y = 0. Existing Monte-Carlo
event generators are unable to simultaneously describe both results. Comparisons of charged-hadron
multiplicities between xenon-xenon and lead-lead collisions at similar collision energies show that
particle production at midrapidity is strongly dependent on the collision geometry in addition to the
system size and collision energy |
