Midrapidity production of pi(+/-), K-+/-, and (<(p))over bar>p measured by the ALICE experiment at the CERN Large Hadron Collider, in Pb-Pb and inelastic pp collisions at root s(NN) = 5.02 TeV, is presented. The invariant yields are measured over a wide transverse momentum (p(T)) range from hundreds of MeV/c up to 20 GeV/c. The results in Pb-Pb collisions are presented as a function of the collision centrality, in the range 0-90%. The comparison of the P-T -integrated particle ratios, i.e., proton-to-pion (p/pi) and kaon-to-pion (K/pi) ratios, with similar measurements in Pb-Pb collisions at root s(NN) = 2.76 TeV show no significant energy dependence. Blast-wave fits of the p(T) spectra indicate that in the most central collisions radial flow is slightly larger at 5.02 TeV with respect to 2.76 TeV. Particle ratios (p/pi, K/pi) as a function of p(T) show pronounced maxima at p(T) approximate to 3 GeV/c in central Pb-Pb collisions. At high p(T) , particle ratios at 5.02 TeV are similar to those measured in pp collisions at the same energy and in Pb-Pb collisions at root sNN = 2.76 TeV. Using the pp reference spectra measured at the same collision energy of 5.02 TeV, the nuclear modification factors for the different particle species are derived. Within uncertainties, the nuclear modification factor is particle species independent for high p(T) and compatible with measurements at root sNN = 2.76 TeV. The results are compared to state-of-the-art model calculations, which are found to describe the observed trends satisfactorily.
