Energy and system dependence of nuclear modification factors of inclusive charged particles and identified light hadrons measured in p--Pb, Xe--Xe and Pb--Pb collisions with ALICE

Abstract

We report recent ALICE results on primary charged particle and neutral meson production in pp, p--Pb, Pb--Pb and Xe--Xe collisions at LHC energies. In this article, measurements of the nuclear modification factors $R_{\mathrm{AA}}$ of primary charged particles and of light neutral mesons in Pb--Pb, in Xe--Xe and in p--Pb collisions in a wide $p_{\mathrm{T}}$ range and different centrality classes are discussed. We compare the nuclear modification factors obtained for different collision systems as a function of transverse momentum, collision centrality as well as charged particle multiplicity ($\mathrm{d}{N}_{\mathrm{ch}}/\mathrm{d}\eta$). We also present comparison of experimental results to model calculations.
