Abstract

We present the preliminary measurement of azimuthal correlations between non-photonic electrons and charged hadrons in p+p collisions at $s_{N N} = 200$ GeV from STAR. The results are compared to PYTHIA simulations to estimate the relative contributions of $D$ and $B$ meson semi-leptonic decays to the non-photonic electrons.
