Description
The ALICE experiment at the LHC is designed to study the hot and dense medium produced in ultra-relativistic heavy-ion collisions. Light-flavour hadrons, such as pions, kaons, protons, strange hadrons, resonances and (hyper)nuclei are optimal probes to characterise the bulk properties of the medium. This is achieved by studying particle hadro-chemistry, with a focus on strangeness production, and investigating a variety of effects, such as the impact of collective flow on the baryon-to-meson ratios, the re-scattering and regeneration in the hadronic gas, which distort hadron spectra and modify resonance yields, and the coalescent production of (hyper)nuclei. By changing the collision systems from elementary hadronic interactions to heavy-ion collisions and the collision energy, one can explore the properties of hot matter in detail. In this talk, we discuss recent ALICE results on light-flavour hadron production across different collision systems from LHC Run 2. The results are compared to lower energy measurements and to model predictions in a wide range of system sizes and collision energies.
