Light-flavour hadron production in p–Pb collisions measured with the ALICE detector at the LHC

The LHC has recently provided p–Pb collisions at sNN=5.02 TeV which play a fundamental role in the understanding of cold nuclear matter effects in heavy ion collisions, providing essential information to discriminate between initial and final state effects. Results from two-particle correlation measurements have revealed an unexpected double ridge structure in these collisions, which could be interpreted either as a sign of collective flow or as an initial state effect related to saturation phenomena. In this paper we present results on identified particles as a function of multiplicity, to investigate possible indications of radial flow. Charged and weakly decaying neutral particles are reconstructed in the ALICE central barrel over a wide momentum range and identified by employing different subsystems and techniques. Transverse momentum spectra of primary charged particles and identified light flavoured hadrons have been measured. The yields, average pTpT and particle ratios are reported as functions of multiplicity, and compared to other collision systems and theoretical models.
