Abstract

We report on measurements of the Y(1S), Y(2S), and Y(3S) differential cross sections (d(2)sigma/dp(T)dy)(y<0.4) , as well as on the &UUpsilon;(1S) polarization in p<(p)over bar> collisions at roots = 1.8 TeV using a sample of 77+/-3 pb(-1) collected by the collider detector at Fermilab. The three resonances were reconstructed through the decay Y-->mu(+)mu(-) . The measured angular distribution of the muons in the Y(1S) rest frame is consistent with unpolarized meson production.
