PHENIX Experiment Results from the RHIC Beam Energy Scan Program

TL;DR

The PHENIX experiment at RHIC conducted a beam energy scan to search for the QCD critical point, measuring various observables, but found no significant evidence of its existence.

Contribution

This study provides comprehensive measurements across multiple energies, offering valuable data to understand the QCD phase diagram and critical phenomena.

Findings

No significant signals of the QCD critical point detected.

Measured fluctuations and correlations consistent with non-critical behavior.

Data contribute to constraining the location of the critical point.

Abstract

The PHENIX Experiment at RHIC has conducted a beam energy scan at several collision energies in order to search for signatures of the QCD critical point and the onset of deconfinement. PHENIX has conducted measurements of transverse energy production, muliplicity fluctuations, the skewness and kurtosis of net charge distributions, Hanbury-Brown Twiss correlations, charged hadron flow, and energy loss. The data analyzed to date show no significant indications of the presence of the critical point.
