Description

The suppression of high $p_{T}$ hadrons in 200 GeV Au+Au collisions at RHIC has been seen as a signature for a partonic medium being formed. The evolution of this key QGP signature is a powerful tool for studying the QCD phase structure in the RHIC Beam Energy Scan (BES). In this talk, we will present measurements of identified $\pi^{\pm}$, $K^{\pm}$, and $p(\bar{p})$ and unidentified charged particles in Au+Au collisions at $\sqrt{s_{NN}}=$7.7, 11.5, 19.6, 27, 39, and 62.4 GeV. We will report nuclear modification factors $R_{CP}$ and $R_{AA}$ where published p+p references are available. These results offer insight into the $\sqrt{s_{NN}}$ dependence of high $p_{T}$ suppression in nuclear collisions.
