Sumario:<!--HTML-->Transverse momentum distributions of identified particles have been measured in several multiplicity classes in p-Pb collisions at sqrt(s_NN) = 5.02 TeV. This measurement can shed light on the understanding of possible collective effects in high multiplicity events. Furthermore p-Pb collisions bridge the charged multiplicity gap between pp and low multiplicity Pb&ndash;Pb collisions. Studying the particle production in this region can improve the understanding of the underlying production mechanisms. Particles are reconstructed with the central barrel detectors over a wide transverse momentum range (from 0 up to 15 GeV/c), exploiting different identification techniques.<br /> &nbsp;<br /> Primary charged particles (pions, kaons, protons, antiprotons, deuterons and anti-deuterons) are identified by their specific energy loss (dE/dx) and time-of-flight. Weakly decaying particles are identified by their characteristic decay topology. Particle-production yields, spectral shapes and particle ratios have been measured in several multiplicity classes. Comparisons with models and results obtained in Pb-Pb collisions at sqrt(s_NN) = 2.76 TeV and pp collisions at 7 TeV at the LHC will be presented.</span><br />
