Abstract

The paper presents recent PHENIX results for the nuclear modification factor R_AA in Au + Au Collisions at sqrt(s_NN) = 200 GeV for the electrons originating from semi-leptonic decays of open heavy flavor carrying particles. We also report the results of the azimuthal asymmetry (v_2) measurement for those electrons, which is directly related to the heavy quark elliptic flow.
