摘要：

The PHENIX experiment at RHIC collected a large data set of d + Au collisions in 2008, reaching to high mass (m(e+e-) < 14 GeV/c(2)) and high transverse momentum (PT < 8 GeV/c). The large range in mass and PT covers the phase space dominated by heavy flavor and so can be used to extract the heavy flavor cross-section. In this proceedings, we present the d + Au dielectron mass spectrum studied as a function of pT and also discuss the impact of using PYTHIA or MC@NLO generators on the cross-section extraction of heavy flavor. The procedure utilizes a double differential fit done in m(e+e-) and PT space, thus providing sensitivity to the regions where either charm or bottom dominates. (C) 2014 CERN.
