Latest Results on Light Flavour Hadron Production at LHC and RHIC

The ultimate goal of heavy-ion collisions is to study the properties of the deconfined medium known as the Quark-Gluon-Plasma. Light flavour hadrons allow investigation of the bulk properties of the created medium. The light flavour particle densities at mid-rapidity allow for the study of the hadrochemistry of the event and comparison with the statistical hadronization model provide a crucial understanding of the hadronization and freeze-out temperatures. On the other hand, the shape of the transverse momentum distributions of identified hadrons at low and intermediate transverse momentum, and their evolution with the collision centrality allow constraints to be placed on the collective expansion properties of the fireball. In this review, I will discuss some recent results on light flavour hadron production at LHC and RHIC energies in the context of freeze-out temperatures in heavy-ion collisions, and the collectivity and strangeness enhancement in small collision systems.
