Nuclear Modification Factors, Directed And Elliptic Flow Of Electrons From Open Heavy Flavor Decays In Au Plus Au Collisions From Star

We present the analyses of single electrons from semileptonic bottom and charm hadron decays at mid-rapidity in root s(NN) = 200 and 54.4 GeV Au+Au collisions (talk in Heavy-Flavor session III). The data at root s(NN) = 200 GeV incorporate information from the Heavy Flavor Tracker which enables the topological separation of electrons originating from bottom and charm hadron decays. We report the first STAR measurements at root s(NN) = 200 GeV of v(2) for bottom decay electrons as a function of p(T) and v(1) for charm decay electrons as a function of electron rapidity. Additionally, we present the improved measurements of heavy-flavor decay electron RAA and a new measurement of the ratio of RCP between bottom and charm decay electrons. Finally, we also report the measurement of non-photonic electron v(2) in root s(NN) = 54.4 GeV data collected during the 2017 RHIC run.
