Description

Measurement of heavy flavor production in proton-proton collisions tests the validity of the pQCD frameworks for the heavy quark production. It also provides a baseline for the interpretation of heavy flavor production in nucleus-nucleus collisions. We present an improved measurement of non-photonic electron (NPE) production at high transverse momentum (2.5<$p_{T}$<12 GeV/c) in proton-proton collisions at $\sqrt{s}=$200 GeV. The result is based on about 24 pb$^{-1}$ data recorded during the year 2012 run by the STAR experiment at the Relativistic Heavy Ion Collider. The measured NPE production cross-section will be compared to pQCD model calculations [1]. [1] R.E. Nelson, R. Vogt and A.D. Frawley, Phys. Rev. C 87, 014908 (2013).
