2 We report on a measurement of the Υ(1S+2S+3S) → e $^{+}$e − cross section at midrapidity in p + p collisions at √$_{s}$ = 200 GeV. We find the cross section to be 114 ± 38 (stat. + fit) +23 − 24 (syst.) pb. Perturbative QCD calculations at next-to-leading order in the Color Evaporation Model are in agreement with our measurement, while calculations in the Color Singlet Model underestimate it by 2 σ . Our result is consistent with the trend seen in world data as a function of the center-of-mass energy of the collision and extends the availability of Υ data to RHIC energies. The dielectron continuum in the invariant mass range near the Υ is also studied to obtain a combined cross section of Drell-Yan plus b - ¯ b → e $^{+}$e $^{−}$.
