Strangeness production from SPS to LHC
F. Becattini, J. Manninen (University, INFN Florence)
TL;DR
This paper reviews strangeness production in heavy ion collisions from SPS to LHC energies, comparing experimental data with statistical models and explaining recent RHIC results through a superposition of equilibrated hadron gas and nucleon-nucleon collision emissions.
Contribution
It introduces a comprehensive comparison of strangeness production data with statistical models and proposes a superposition model to explain RHIC observations.
Findings
RHIC data on strange particles align with a superposition of equilibrated hadron gas and nucleon-nucleon collisions.
Statistical models effectively describe strangeness production across different energies.
Canonical suppression mechanisms are significant in understanding strangeness yields.
Abstract
Global strangeness production in relativistic heavy ion collisions at SPS and RHIC is reviewed. Special emphasis is put on the comparison with the statistical model and the canonical suppression mechanism. It is shown that recent RHIC data on strange particle production as a function of centrality can be explained by a superposition of a fully equilibrated hadron gas and particle emission from single independent nucleon-nucleon collisions in the outer corona.
