Measurement of the Upsilon(nS) cross section at CDF

<p>Since the bound <em>bb¯</em> system was first discovered, researchers have been trying to explain the production mechanism for quarkonium to learn more about this system. Several different theories try to describe quarkonium production, and while these theories agree with experimental measurements of production rates, theoretical predictions for quarkonium polarization vary. Careful measurement of the ϒ(<em> nS</em>) angular distribution along with the ϒ(<em>nS</em>) cross section can provide insight into the quarkonium production mechanism. This analysis measures the ϒ(<em>nS</em>) cross section and ϒ(1<em> S</em>) polarization parameters.</p>
