Comparison of nudyn[+,-] values against charged particle density for pp, p-Pb, Pb-Pb and Xe-Xe collisions at LHC energies. Comparison with MC models is also shown.

Detail description

Dependence of nudyn[+,-]  for pp at √s= 5.02 TeV, p-Pb at √sNN = 5.02 TeV, Pb-Pb at √sNN = 2.76 and 5.02 TeV and Xe-Xe collisions at √sNN = 5.44 TeV as  a function of charged particle multiplicity.  ALICE data are compared with MC models.
