Non-photonic electron production in p$+$p collisions at $\surd s =$ 200 GeV

High precision measurements of heavy flavor production in proton-proton collisions are instrumental to test the validity and constrain the parameters of pQCD calculations of heavy quark production. They also provide a baseline for the interpretation of heavy flavor production in heavy-ion collisions. In this talk, we present an improved measurement of non-photonic electron (NPE) production from semi-leptonic decay of open heavy flavor hadrons in proton-proton collisions at $\surd $s$=$200 GeV by the STAR experiment at the Relativistic Heavy Ion Collider. The results cover a wide range of transverse momentum, 0.2\textless p$_{\mathrm{T}}$\textless 12 GeV/c. The results for 2.5\textless p$_{\mathrm{T}}$\textless 12 GeV/c are based on about 24 pb$^{-1}$ of data triggered on energy deposited in the electromagnetic calorimeter, while the results for 0.2\textless p$_{\mathrm{T}}$\textless 2.5 GeV/c are extracted using about 300 M minimum-bias events. The measured NPE production cross-section is compared to previous STAR and PHENIX experimental results, as well as pQCD model calculations.
