Description
Transverse momentum spectra of charged particles are important baseline measurements of perturbative QCD particle production in pp collisions and, in Pb-Pb collisions, they provide insight on the parton energy loss in the hot and dense QCD medium. In this contribution we present the ALICE measurements of transverse momentum spectra in pp and Pb-Pb collisions at the unprecedented energy of $\sqrt{s_\mathrm{NN}}=5.02$ TeV. Measurements in Pb-Pb collisions are obtained as a function of the centrality of the collision and presented in terms of the nuclear modification factor $R_{\mathrm{AA}}$. The results are compared to previous measurements at lower collision energy and confronted with theoretical expectations from Monte Carlo event generators (pp) and model calculations of in-medium jet quenching (Pb-Pb).
