Non-photonic electron-hadron azimuthal correlation for AuAu, CuCu and pp collisions at image Original Research Article

We present preliminary STAR results of azimuthal correlations between non-photonic electrons and hadrons in AuAu, CuCu and pp at View the MathML source. Comparison of the e-h correlations from these colliding systems allows one to study the system-size dependence of heavy quark jet-medium interactions. We also report on the relative charm and bottom contributions to non-photonic electrons extracted from correlations measured in pp collisions. Our results, when combined with RAA measurements of non-photonic electrons, constrain the charm and bottom energy loss in the dense medium.
