Abstract

The PHENIX Collaboration carries out a comprehensive physics program which studies heavy flavor production in relativistic heavy ion collisions at RHIC. The discovery at RHIC of large high-pT suppression and flow of electrons from heavy quarks flavors have altered our view of the hot and dense matter formed in central Au+Au collisions at GeV. These results suggest a large energy loss and flow of heavy quarks in the hot, dense matter. In recent years, the PHENIX has installed a silicon vertex tracker both in central rapidity (VTX) and in forward rapidity (FVTX) regions, and has collected large data samples. These two silicon trackers enhance the capability of heavy flavor measurements via precision tracking. This paper summarizes some of the latest PHENIX results concerning open heavy flavor and quarkonia production as a function of rapidity, energy and system size.

Highlights

At center of accelerator over the years [4]
Researchers at RHIC have made a major physics discovery, namely the creation of a new form of matter in high-energy central gold–gold collisions. This matter, dense and strongly interacting, is called the strongly coupled quark-gluon plasma, or sQGP. This finding of a new form of matter was published in four independent white papers [5] from the four RHIC experiments
The extended particle momentum range at RHIC allowed the use of hard probes to study the behavior of the created medium that was difficult to access at lower collision energies

Summary

Introduction

At center of accelerator over the years [4]. Researchers at RHIC have made a major physics discovery, namely the creation of a new form of matter in high-energy central gold–gold collisions. 2. Recent Open Heavy Flavor and Quarkonia Results The measurement of inclusive hadron yields in central Au+Au collisions at RHIC led to the discovery of the suppression of hadron production at large transverse momenta (pT ) compared to p + p collisions [5].
