Abstract

We report on measurements of the

ϒ (1 S)

,

ϒ (2 S)

, and

ϒ (3 S)

differential,

{(\frac{d^{2} σ}{d P_{t} dy})}_{y = 0}

, and integrated cross sections in

p \bar{p}

collisions at

\sqrt{s} = 1.8

TeV using a sample of 16.6 ± 0.6

{pb}^{- 1}

collected by the Collider Detector at Fermilab. The three resonances were reconstructed through the decay

ϒ \to μ^{+} μ^{-}

. Comparison is made to a leading order QCD prediction.
