R. Cropp (CDF collaboration)
TL;DR
This paper presents recent experimental results from the CDF collaboration on the production rates, feeddown contributions, and polarization states of various quarkonium states such as J/Psi, Psi(2S), and Upsilon in proton-antiproton collisions at 1.8 TeV.
Contribution
It provides new measurements of quarkonium production and polarization, enhancing understanding of quarkonium production mechanisms in high-energy hadron collisions.
Findings
Measured Upsilon production cross sections.
Quantified Upsilon(1S) from Chi_b feeddown.
Analyzed polarization of J/Psi, Psi(2S), and Upsilon(1S).
Abstract
CDF has obtained new results on quarkonium production in p\bar{p} collisions at \sqrt{s} = 1.8 TeV. We report on measurements of Upsilon meson production, Upsilon(1S) production from Chi_b feeddown, and the production polarization of Upsilon(1S), J/Psi and Psi(2S) mesons.
