Phase Transition Signature Results from PHENIX

TL;DR

The PHENIX experiment searched for signs of the QCD critical point through various fluctuation and correlation measurements but found no significant evidence of critical behavior in the studied collision systems.

Contribution

This work provides comprehensive fluctuation and correlation measurements across multiple systems and energies to search for the QCD critical point.

Findings

No significant evidence of critical behavior detected

Measurements across different systems and energies

Discussion of interesting features without conclusive critical signals

Abstract

The PHENIX experiment has conducted searches for the QCD critical point with measurements of multiplicity fluctuations, transverse momentum fluctuations, event-by-event kaon-to-pion ratios, elliptic flow, and correlations. Measurements have been made in several collision systems as a function of centrality and transverse momentum. The results do not show significant evidence of critical behavior in the collision systems and energies studied, although several interesting features are discussed.
