We report on measurements of the Υ(1S), Υ(2S), and Υ(3S) differential cross sections (d2σ/dpTdy)|y|<0.4, as well as on the Υ(1S) polarization in pp¯ collisions at s√=1.8TeV using a sample of 77±3pb−1 collected by the collider detector at Fermilab. The three resonances were reconstructed through the decay Υ→μ+μ−. The measured angular distribution of the muons in the Υ(1S) rest frame is consistent with unpolarized meson production.
