【 摘 要 】

We present the STAR preliminary results of the azimuthal correlations between non-photonic electrons and charged hadrons at mid-rapidity in p+p collisions at √s = 200 GeV and 500 GeV. The correlation distributions are fitted with PYTHIA templates to extract the relative contribution from bottom decays to non-photonic electrons. This could provide a precise p+p reference for the study of bottom production in heavy-ion collisions at RHIC.
