Exploring sQGP and Small Systems

TL;DR

This paper reviews the properties of the strongly interacting Quark-Gluon Plasma (sQGP) created in high-energy heavy ion collisions and discusses recent findings from small systems like p+p and p+A collisions, highlighting similarities to heavy ion behavior.

Contribution

It provides a comprehensive review of sQGP as a nearly perfect liquid and explores the transition from small systems to heavy ions based on recent LHC results.

Findings

sQGP behaves as a nearly perfect liquid with low viscosity

Small systems show similarities to heavy ion collisions at high multiplicities

Future measurements could further elucidate the transition dynamics

Abstract

A strongly interacting Quark-Gluon Plasma (sQGP) is created in the high energy heavy ion collisions at RHIC and LHC. Our present understanding of sQGP as a very good liquid with astonishingly low viscosity is reviewed. With the arrival of the interesting results from LHC in high-energy p+p and p+A, a new endeavour to characterize the transition from these small systems to heavy ions (A+A) is now in place, since, even the small systems showed prominent similarities to heavy ions in the rising multiplicity domains. An outlook of future possibilities for better measurements is also made at the end of this brief review.
