The measurement of non-photonic electrons in STAR
Original language description
The measurements of non-photonic electrons (NPE), mainly produced by semileptonic decays of D and B mesons, provide information on heavy quarks production as well as properties of nuclear matter produced in heavy ion collisons. In order to interpret theNPE measurements it is important to determine the relative charm and bottom contribution to the NPE spectrum. In this proceedings we present the measurements of NPE spectra and NPE-hadron azimuthal correlations in p+p collisions at root s=200 GeV and atroot s=500 GeV. NPE-hadron correlations allow extraction of the B decay contribution to the NPE. The B decay contribution is comparable to the contribution from the D meson decay at root s=200 GeV at p(T) higher than 5 GeV/c, and is about 60% at root s=500 GeV at P-T higher than 5 GeV/c. STAR measured NPE spectrum in p+p collisions as well as relative constribution of bottom decays to the spectrum is consistent with FONLL pQCD calculations. The preliminary results of NPE spectra and NPE-
