The nuclear modification of charged particles in Pb-Pb at $\sqrt{{\text{s}}_{\text{NN}}}=\text{5.02}\text{TeV}$ measured with ALICE

Abstract

The study of inclusive charged-particle production in heavy-ion collisions provides insights into the density of the medium and the energy-loss mechanisms. The observed suppression of high-${\text{p}}_{\text{T}}$ yield is generally attributed to energy loss of partons as they propagate through a deconfined state of quarks and gluons - Quark-Gluon Plasma (QGP) - predicted by QCD. Such measurements allow the characterization of the QGP by comparison with models. In these proceedings, results on high-${\text{p}}_{\text{T}}$ particle production measured by ALICE in Pb-Pb collisions at $\sqrt{{\text{s}}_{\text{NN}}}=5.02\mathrm{TeV}$ as well as well in pp at $\sqrt{\text{s}}=5.02\mathrm{TeV}$ are presented for the first time. The nuclear modification factors (${\text{R}}_{\text{AA}}$) in Pb-Pb collisions are presented and compared with model calculations.
