Abstract In this Letter, comprehensive results on π±,K±,KS0, p(p¯) and Λ(Λ¯) production at mid-rapidity (0 < yCMS < 0.5) in p-Pb collisions at sNN = 5.02 TeV, measured by the ALICE detector at the LHC, are reported. The transverse momentum distributions exhibit a hardening as a function of event multiplicity, which is stronger for heavier particles. This behavior is similar to what has been observed in pp and Pb--Pb collisions at the LHC. The measured pT distributions are compared to results at lower energy and with predictions based on QCD-inspired and hydrodynamic models.
