Abstract:
A detailed study of the behavior of different observables that characterize the violence and the dynamics of a collisions, as a function of the Color Glass Condensate inspired scaling variable is presented. The latest results measured at LHC in terms of Xe-Xe collisions are used in this study, and a comparison in terms of the dependence of mean pT, of the slope of the mean pT as a function of mass and of the Boltzmann Gibbs Blast Wave parameter, the average collective flow velocity betaT, on the scaling variable, for several collisions systems (Cu-Cu, Au-Au, Pb-Pb and Xe-Xe) at different energies (200 GeV, 5.02 TeV and 5.44 TeV) will be discussed. Furthermore, the evidenced similarities between small systems (pp) and heavy ion collisions at LHC energies are also considered, results of the comparison between pp, Pb-Pb and Xe-Xe systems at LHC energies in terms of the dependence of the same observables on the scaling variable are also presented, including preliminary results for pp collisions at 13 TeV.
