| dc.description | We compare the non-photonic electron and $D^{0}$ meson $p_{T}$ distributions measured at RHIC with the PYTHIA Monte Carlo event generator in p+p collisions at $\sqrt{s_{NN}}=200$ GeV. A delta fragmentation function much harder than the Peterson function, consistent with recombination scheme for charm meson formation, is needed to match the experimental data. Attempts to fit the non-photonic electrons at high $p_{T}$ show large uncertainties and the $B$ meson semi-leptonic decays may not be dominant for electron $p_{T}$ up to 8 GeV/c. Correlations of non-photonic electrons with charged hadrons are studied. We propose an experimental method to quantitatively determine the relative contributions of $D$ and $B$ meson semi-leptonic decays to the non-photonic electrons. | |
