Title: A New Measurement of Charm and Bottom Production from Semielectronic Hadron Decays in p+p Collisions at RHIC

Speaker: Javier Orjuela Koop (Univ. Colorado, Boulder)

Abstract: This talk will present a new measurement of the differential production of open heavy flavor hadrons in p+p collisions at sqrt(s) = 200 GeV. The measurement proceeds via a displaced vertex analysis of electron tracks from the decay of charm and bottom hadrons, using the PHENIX Silicon Vertex Detector. The smaller uncertainties and extended kinematic reach of this result constitute an improvement over previous measurements, providing valuable new data to constrain pQCD calculations, and a new baseline for future precision measurements of heavy flavor suppression at RHIC.
