Query: Measurement of Non-Photonic Electron Angular Correlations with Charged
  Hadrons   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.
