Abstract

Measurements of the differential production of electrons from open-heavy-flavor hadrons with charm- and bottom-quark content in $p + p$ collisions at $\sqrt{s} = 200 GeV$ are presented. The measurements proceed through displaced-vertex analyses of electron tracks from the semileptonic decay of charm and bottom hadrons using the PHENIX silicon-vertex detector. The relative contribution of electrons from bottom decays to inclusive heavy-flavor-electron production is found to be consistent with fixed-order-plus-next-to-leading-log perturbative-QCD calculations within experimental and theoretical uncertainties. These new measurements in $p + p$ collisions provide a precision baseline for comparable forthcoming measurements in $A + A$ collisions.
