Description

Recent results on particle production in p--Pb collisions at the LHC exhibit features that are similar to those observed in Pb-Pb collisions. This indicates that final-state collective effects might also be present in small collision systems. In order to quantify the effects, the transverse momentum spectra (pT) of charged particles, identified hadrons and jets measured in different multiplicity/centrality intervals in p-Pb collisions at sqrt(sNN)=5.02 TeV are compared with results from pp and Pb-Pb collisions, all measured in the ALICE experiment. The obtained results are compared with theoretical models. Charged-particle tracks are reconstructed at mid-rapidity over a large momentum range 0.15 < pT < 50 GeV/c. Light-flavor hadrons and resonances are identified in the broad momentum range from 0.15 GeV/c up to 15 GeV/c using several particle identification techniques. Jets are reconstructed at mid-rapidity in the momentum range 20 < pT < 120 GeV/c by the anti-kT algorithm with resolution parameter R=0.2--0.4.
