From Strangeness Enhancement to Quark-Gluon Plasma Discovery

TL;DR

This paper reviews three decades of experimental efforts to detect quark-gluon plasma, focusing on signatures like strangeness enhancement, and discusses the progress made at major collider facilities.

Contribution

It provides a comprehensive survey of experimental signatures and the evolution of QGP detection methods over time.

Findings

Strangeness enhancement observed at multiple colliders.

Progress in identifying QGP signatures over three decades.

Experimental results support the existence of quark-gluon plasma.

Abstract

This is a short survey of signatures and characteristics of the quark-gluon plasma in the light of experimental results that have been obtained over the past three decades. In particular, we present an in-depth discussion of the strangeness observable, including a chronology of the experimental effort to detect QGP at CERN-SPS, BNL-RHIC, and CERN-LHC.
