| dc.description | Correlations of non-photonic electrons with charged hadrons are studied using the PYTHIA Monte Carlo event generator in p+p collisions at $\sqrt{s_{NN}} = 200$ GeV. We propose experimental methods to estimate the relative contributions to non-photonic electrons from charm and bottom decays. We present the measurement of azimuthal correlations between non-photonic electrons and charged hadrons in p+p collisions at $\sqrt{s_{NN}} = 200$ GeV from STAR. The results are compared to PYTHIA simulations to estimate the relative contributions of $D$ and $B$ meson semi-leptonic decays to non-photonic electrons. Our preliminary result indicates that at $p_{T} \sim 4.0 - 6.0$ GeV/c the measured $B$ contribution to non-photonic electrons is comparable to $D$ contribution, and is consistent with the FONLL calculation. | |
