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 ($\pi$, 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 shap...

description Comprehensive results on transverse momentum distributions and their ratios for identified light flavor hadrons ($\pi$, 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.
