Does the fireball found in AuAu collisions at RHIC resemble plasma?

TL;DR

This paper compares the properties of the fireball created in RHIC AuAu collisions with those of an ideal electromagnetic plasma, exploring whether the hadron matter exhibits plasma-like signatures.

Contribution

It provides a comparative analysis highlighting similarities and differences between the RHIC fireball and electromagnetic plasma, and discusses future research directions.

Findings

Fireball properties are not contrary to plasma signatures.

Current data are limited for definitive conclusions.

Further studies are needed to confirm plasma-like behavior.

Abstract

General properties of the hot and dense hadron matter (fireball) discovered in AuAu collisions with pSNN = 130 and 200 GeV at RHIC are compared with these for ideal electromagnetic plasma. None of them was found to be in contrary to those of the plasma typical signs distinguishing its from other aggregate states of the matter. The author notes that modern experimental data about the fireball properties are limited to make their comprehensive comparison with plasma signatures. The author also points out the directions needed to be studied to answer question whether the hadron matter observed in the RHIC experiments is a color analogue of the electromagnetic plasma or not.
