Abstract

Heavy quarks (charm and bottom) are produced early in the collisions and therefore are important probes of the hot and dense matter created in the reactions at RHIC energies. Electrons from semileptonic decays of heavy flavor hadrons, e^HF, are the most feasible tool so far for studying heavy quarks energy loss at Relativistic Heavy Ion Collider (RHIC) energies. Measurements of e^HF nuclear modification factor and azimuthal anisotropy v₂ are of particular interest because they provide essential means for understanding the heavy quark in-medium interactions. In this paper, we report on a precision measurement of heavy flavor electron p_T spectra and azimuthal anisotropy in Au+Au collisions at 200 GeV.
