Measurements of electrons from heavy-flavor hadron decays in 27, 54.4, and 200 GeV Au+Au collisions in STAR

In these proceedings, we present the measurements of nuclear modification factors for electrons from open charm ( c→e ) and bottom hadron decays b→e at mid-rapidity region in Au+Au collisions √ S NN = 200 GeV. The significance difference between is ≥ 3σ. We also elliptic flow v 2 inclusive heavy-flavor decayed (HFE) 27 54.4 results show non-zero HFE GeV a hint smaller than those
