The production of heavy quarkonium in hadronic collisions provides an ideal testing ground for our understanding of the production mechanisms for heavy quarks and the non-perturbative QCD effects that bind the quark pairs into quarkonium. In this analysis, the inclusive production cross section of the Υ(1S) bottomonium state is measured using the Υ(1S) → μ⁺μ^- decay mode. The data sample corresponds to an integrated luminosity of 159.1 ± 10.3 pb^-1. We determine differential cross sections as functions of the Υ(1S) transverse momentum, p_T^Υ, for three ranges of the Υ(1S) rapidity: 0 < |y^Υ| < 0.6,0.6 < |y^Υ| < 1.2 and 1.2 < |y^Υ| < 1.8. The shapes of dσ/d_pT cross sections show little variation with rapidity and are consistent with the published Run I CDF measurement over the rapidity range |y^Υ| < 0.4.
