Light flavor hadron spectra at low p_T and search for collective phenomena in high multiplicity pp, p–Pb and Pb–Pb collisions measured with the ALICE experiment

Comprehensive results on transverse momentum distributions and their ratios for identified light flavor hadrons (π, K, p) at low p_T and mid-rapidity as a function of charged particle multiplicity are reported for pp collisions at 7 TeV. Particle mass dependent hardening of the spectral shapes in Pb–Pb collisions at 2.76 TeV were attributed to hydrodynamical flow and quantitatively parameterized with Boltzmann–Gibbs Blast Wave fits. In this contribution, we investigate the existence of collective phenomena in small systems: pp, p–Pb and peripheral Pb–Pb where similar patterns are observed in multiplicity dependent studies
