High $p_T$ non-photonic electron production in $p$+$p$ collisions at $\sqrt{s}$ = 200 GeV

We present the measurement of non-photonic electron production at high transverse momentum ($p_T>$ 2.5 GeV/$c$) in $p$ + $p$ collisions at $\sqrt{s}$ = 200 GeV using data recorded during 2005 and 2008 by the STAR experiment at the Relativistic Heavy Ion Collider (RHIC). The measured cross-sections from the two runs are consistent with each other despite a large difference in photonic background levels due to different detector configurations. We compare the measured non-photonic electron cross-sections with previously published RHIC data and pQCD calculations. Using the relative contributions of B and D mesons to non-photonic electrons, we determine the integrated cross sections of electrons ($\frac{e^{+}+e^{-}}{2}$) at 3 GeV/$c < p_T <~$10GeV\mathrm{/}$c$frombottomandcharmmesondecaystobe${d\sigma_{(B\to e)+(B\to D \to e)} \over dy_e}|_{y_e=0}$=4.0$\pm0.5$({\rm stat.})$\pm 1.1$({\rm syst.}) nb and $\frac{d{\sigma }_{D\to e}}{d{y}_e}{\mathrm{\mid }}_{y_e=0}$ = 6.2$\pm 0.7$({\rm stat.})$\pm 1.5$({\rm syst.}) nb, respectively.
