Description
The study of strangeness baryon production in relativistic heavy-ion collisions provides unique insights into the properties of strongly interacting matter at extreme temperature and density. Strangeness enhancement was among the earliest proposed signatures of the formation of the quark-gluon plasma (QGP), and over the past decades, systematic measurements from SPS, RHIC, and LHC experiments have revealed characteristic trends in the yields, spectra, and collective behavior of strange and multi-strange baryons. In particular, the production of hyperons and their resonance states sheds light on the interplay between partonic degrees of freedom and hadronic interactions during the evolution of the fireball.
In this talk, I will present recent results on strangeness baryon production from heavy-ion collisions at the LHC, focusing on the production of hyperons, multi-strange baryons, and strange baryon resonances. Comparisons across beam energies and collision systems allow us to trace the onset of de-confinement, the role of hadronic re-scattering, and the possible formation of exotic bound states.
