Abstract:
The latest experimental results from RHIC to LHC are used in order to study the dependence of different observables on the square root of the hadron multiplicity over unit of rapidity and unit of transverse overlapping area. The most relevant dependencies, like < p_T >, the slopes of < p_T > mass dependence and the Boltzmann-Gibbs Blast Wave fit parameter, < β_T >, will be discussed in this presentation.
This study was conducted for a large range of energies, from 7.7 GeV, up to 5.02 TeV, for both Pb-Pb and Au-Au colliding systems. Similar systematics for pp at 7 TeV are in a good agreement with Pb-Pb at 2.76 and 5.02 TeV. The corona influence to the observed trends is also discussed.
