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.
