Title: Electron-Positron Tomography of Quark-Gluon Plasma

Speaker: Lijuan Ruan (BNL)

Abstract:

 Electron-positron pairs are penetrating probes of Quark-Gluon Plasma created in relativistic heavy ion collisions. They can provide information deep into the system and early time. At STAR, we use electron-positron tomography to study chiral symmetry, temperature, and lifetime of hot, dense medium. In this talk, I will review recent results and discuss

future perspectives.
