Measurement of the Bottom Quark Contribution to Nonphotonic Electron Production in p+p Collisions at {radical}(s)=200 GeV
The contribution of B meson decays to nonphotonic electrons, which are mainly produced by the semileptonic decays of heavy-flavor mesons, in p+p collisions at {radical}(s)=200 GeV has been measured using azimuthal correlations between nonphotonic electrons and hadrons. The extracted B decay contribu...

| description | The contribution of B meson decays to nonphotonic electrons, which are mainly produced by the semileptonic decays of heavy-flavor mesons, in p+p collisions at {radical}(s)=200 GeV has been measured using azimuthal correlations between nonphotonic electrons and hadrons. The extracted B decay contribution is approximately 50% at a transverse momentum of p{sub T{>=}}5 GeV/c. These measurements constrain the nuclear modification factor for electrons from B and D meson decays. The result indicates that B meson production in heavy ion collisions is also suppressed at high p{sub T}. |
