Abstract
The measurement of strangeness production is one of the powerful tools to study the thermal properties of the QGP and while strangeness enhancement is a well established experimental observation in heavy ion collisions, its interpretation is still debated. In particular the study of (multi-)strangeness particle production as a function of the event multiplicity in different collision systems, reported by ALICE, has shown a smooth increase of strange particle yields with respect to yields of non-strange particles. In this proceedings, we present the latest results on multiplicity-dependent strangeness production in different colliding systems at LHC energies.
Furthermore, recent measurements of mesonic and baryonic resonances will be presented to investigate how hadronic scattering processes affect measured resonance yields. The experimental results obtained in pp, p--Pb and Pb--Pb collisions will also be compared with the theoretical predictions.
