Abstract
Details of the measurement of the production of open heavy flavor hadrons with bottom and charm
quark content in p + p collisions at $\sqrt{s_{NN}}$ = 200 GeV are presented. The measurement proceeds
through the use of a distanced of closest approach analysis of electron tracks from the semileptonic decay of bottom and charm hadrons using the PHENIX detector. The relative contribution of electrons from bottom decays to inclusive heavy flavor electron production is found to be consistent with perturbative QCD calculations at fixed-order-plus-next-to-leading-log within experimental and theoretical
uncertainties over the transverse momentum range of 1 GeV/c to 9 GeV/c.
