Quarkonium Production with the CMS Experiment
Keith Ulmer (on behalf of the CMS Collaboration)
TL;DR
This paper reports on measurements of quarkonium production, including chi_c and Upsilon states, and Bc meson reconstruction, using CMS data from 7 TeV proton-proton collisions at the LHC.
Contribution
It provides new experimental measurements of quarkonium production ratios and Bc meson reconstruction in proton-proton collisions at 7 TeV.
Findings
Measured chi_c2/chi_c1 production ratio versus transverse momentum.
Measured Upsilon(nS) production versus rapidity and transverse momentum.
Reconstructed Bc mesons in two decay channels.
Abstract
Results from studies of quarkonium production are presented from the CMS experiment at the LHC in proton-proton collisions at sqrt(s) = 7 TeV. We report measurements of the ratio of chi_c2/chi_c1 production versus transverse momentum and Upsilon(nS) production vs rapidity and transverse momentum for the 1S, 2S and 3S states. Reconstruction of Bc mesons is also presented in two decay channels.
