The Mar(e)k of QGP: Strangeness

TL;DR

This paper reviews how strangeness signatures serve as crucial indicators for identifying quark-gluon plasma, highlighting historical discoveries, experimental results, and models like statistical hadronization and sudden hadronization.

Contribution

It provides a comprehensive overview of the role of strangeness in QGP detection, including recent data analysis and universal hadronization conditions.

Findings

Strangeness and entropy content of large fireballs analyzed.

Universal hadronization condition described across collision systems.

Emphasis on antihyperons' role in QGP signatures.

Abstract

Strangeness signature of of quark-gluon plasma (QGP) is central to the exploration of baryon-dense matter: the search for the critical point and onset of deconfinement. I report on the discovery of QGP by means of strangeness: The key historical figures and their roles in this quest are introduced and the experimental results obtained are discussed. The important role of antihyperons is emphasized. The statistical hadronization model, and sudden hadronization are described. Results of present day data analysis: strangeness and entropy content of a large fireball, and the universal hadronization condition describing key features of all explored collision systems are presented.
