Abstract

We present recent physics results from the STAR experiment at Relativistic Heavy Ion Collider (RHIC). The proceedings cover studies of azimuthal anisotropy in small and large systems, global and local hyperon polarization, correlation femtoscopy, antideuteron and J/ψ production from heavyion program as well as the measurements of longitudinal spin asymmetry from polarized proton program.

Highlights

  • The main goal of high-energy physics is to understand the properties of the strong interaction that can be described by the Quantum Chromodynamics (QCD)

  • This medium is known as Quark-Gluon Plasma (QGP)

  • We report recent results from heavy-ion and polorized proton-proton programs obtained in the Solenoidal Tracker At Relativistic Heavy Ion Collider (RHIC) (STAR) experiment

Summary

Introduction

The main goal of high-energy physics is to understand the properties of the strong interaction that can be described by the Quantum Chromodynamics (QCD). Variation of collision energy provides a unique opportunity to investigate the properties of the created medium on baryon chemical potential (μB) and temperature (T ). This medium is known as Quark-Gluon Plasma (QGP). Studying the high-energy polorized p+p collisions is essential key in understanding of the spin structure of the proton in terms of gluon, quark and antiquark constitiuents. In these proceedings, we report recent results from heavy-ion and polorized proton-proton programs obtained in the Solenoidal Tracker At RHIC (STAR) experiment
