# PHENIX measurements of single electrons from charm and bottom decays at midrapidity in Au+Au collisions

## TL;DR

This paper reports PHENIX's measurements of how charm and bottom quarks' decay electrons are suppressed in central Au+Au collisions at 200 GeV, providing insights into the properties of the Quark-Gluon Plasma.

## Contribution

First separation of charm and bottom decay electron nuclear modification factors in Au+Au collisions at 200 GeV with new data.

## Key findings

- Charm and bottom decay electrons show suppression in central collisions.
- Results help understand energy loss mechanisms in the QGP.
- Data supports models of heavy quark interactions in hot nuclear matter.

## Abstract

Heavy quarks (charm and bottom) are a sensitive probe of the Quark-Gluon Plasma (QGP) created in high-energy nuclear collisions. The modification of their phase-space in the QGP reflects the physical property of the QGP because they are generated in the early stage of collisions and subsequently propagate through the QGP. PHENIX has published the first measurement of the nuclear modification factors $R_{\rm{AA}}$ of separated charm and bottom hadron decay electrons in minimum bias Au+Au collisions at $\sqrt{s_{NN}}$ $=$ 200 GeV using the 2011 data set. In these proceedings, we present $R_{\rm{AA}}({c{\rightarrow}e})$ and $R_{\rm{AA}}({b{\rightarrow}e})$ in most central Au+Au collisions at $\sqrt{s_{NN}}$ $=$ 200 GeV using 1/8 of our large 2014-2016 data set.
