Description

After the successful completion of the first LHC run, a complete dataset of light flavor particles in three collision systems (pp, p-Pb, Pb-Pb) is available for detailed comparisons with thermal model descriptions. These models have been successful in describing particle production in heavy-ion collisions at RHIC and SPS energies. The evolution of particle yields and ratios from RHIC to LHC energies will be discussed. We will present recent fits to the ALICE data and compare the achievable precision in describing different collision systems at different centralities, event multiplicities and center of mass energies. The experimental significance of deviations between data and model will be discussed in detail as well as differences between equilibrium and non-equilibrium thermal models.
