The momentum distribution of electrons from decays of heavy flavor (charm and bottom) for midrapidity |y|< 0.35 in p+p collisions at s=200 GeV has been measured by the PHENIX experiment at the BNL Relativistic Heavy Ion Collider over the transverse momentum range 0.3 < p(T)< 9 GeV/c. Two independent methods have been used to determine the heavy-flavor yields, and the results are in good agreement with each other. A fixed-order-plus-next-to-leading-log perturbative QCD calculation agrees with the data within the theoretical and experimental uncertainties, with the data/theory ratio of 1.71 +/- 0.02(stat)+/- 0.18(sys) for 0.3 < p(T)< 9 GeV/c. The total charm production cross section at this energy has also been deduced to be sigma(cc)=567 +/- 57(stat)+/- 193(sys) mu b.

- Momentum fluctuations of heavy quarks in the gauge-string duality (2006, background): “But in light of the comparisons of pp→ eX PHENIX data [52] with fixed-order-plus-next-to-leading-log calculations [53], it seems ad hoc to neglect bottom contributions completely.”
- Heavy-flavour and quarkonium production in the LHC era: from proton–proton to heavy-ion collisions (2015, methodology): “The sPHENIX running plan consists of two years of data taking (2021–2022) in Au–Au, d–Au and pp collisions at √ sNN = 200 GeV.”
