Contribution

This paper presents new experimental results from PHENIX on QGP signatures in small and large systems, expanding understanding of medium effects in high-energy collisions.

Findings

Evidence of collectivity in small systems

Modification of light hadron and quarkonia production observed

Detailed properties of QGP characterized in large systems

Abstract

PHENIX has performed an extensive study on the evolution of medium effects from small to large systems. PHENIX has continued searching for Quark-Gluon Plasma (QGP) in small systems by measuring collectivity, modification of light hadron and quarkonia production, and jet substructure. In large systems, detailed studies on the property of the QGP have been done using direct photon, $\pi^{0}$-hadron correlation, heavy-flavor electron, and $J/\psi$ flow with a large statistics of data collected in 2014. This report covers new results from the PHENIX experiment in various collision systems.
