Abstract (english)
We present the measurement of nonphotonic electron production at high transverse momentum (pT>2.5  GeV/c) in p+p collisions at √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 nonphotonic electron cross sections with previously published RHIC data and perturbative quantum chromodynamics calculations. Using the relative contributions of B and D mesons to nonphotonic electrons, we determine the integrated cross sections of electrons (e++e-/2) at GeV/c<pT<10  GeV/c from bottom and charm meson decays to be [(dσ(B→e)+(B→D→e))/(dye)]ye=0=4.0±0.5(stat)±1.1(syst)  nb and [(dσD→e)/(dye)]ye=0=6.2±0.7(stat)±1.5(syst)  nb, respectively.
