Abstract

The observation of long range correlations in highly asymmetric systems, as in p+Pb and d+Au collisions, suggests a creation of a medium with collective behavior. It is still an open question if the quark-gluon plasma is formed in these collision. Hence, the RHIC collider invested time to study the small systems in different collision systems and energies. Here we discuss the recent results from the PHENIX and STAR collaborations in four different collision systems p+Al, p+Au, d+Au and 3He+Au at [see formula in PDF] = 200 GeV, and also for the energy scan in d+Au collisions between [see formula in PDF] = 19.6 – 200 GeV.

Highlights

  • The study of non-perturbative aspects of QCD is one of the main goals of high energy nuclear collisions

  • This proceedings present the recent results from the RHIC collider experiment on the small collision systems

  • The data suggest a smooth transition from p + p to heavy ion collisions

Summary

Introduction

The study of non-perturbative aspects of QCD is one of the main goals of high energy nuclear collisions. The recent measurements of flow-like behavior in small-on-large collision systems at LHC [1] and RHIC energies [2] prompted a large interest in studying the possible creation of a quark-gluon droplet in these systems. The non-zero azimuthal anisotropy is the first observed signature of possible formation of a collective medium in small collision systems. It is very important to study the other signatures of the QGP in order to confirm the medium creation in these small systems. This proceedings focuses on the collective motion, and on the jet quenching phenomena and the strangeness production in small systems
