$\Upsilon$ Production and Spin Alignment in $p \overline{p}$ Collisions at $\sqrt{s} = 1.96$ TeV

We report on measurements of the $\Upsilon$(1S), $\Upsilon$(2S) and $\Upsilon$(3S) differential cross sections ($d^2\sigma/dp_T dy)_{|y|<0.6}$, as well as on the $\Upsilon$ spin alignment in $p \overline{p}$ collisions at $\sqrt{s} = 1.96$ TeV using a sample of 360~pb$^{-1}$ collected by the CDF II detector. The three resonances were reconstructed through the decay $\Upsilon \rightarrow \mu^{+} \mu^{-}$.
