Quarkonium production in the LHC era: a polarized perspective
Pietro Faccioli, Valentin Knuenz, Carlos Lourenco +2
Polarization measurements are usually considered as the most difficult challenge for the QCD description of quarkonium production. In fact, global data fits for the determination o…
Heavy quarkonium: progress, puzzles, and opportunities
N. Brambilla, S. Eidelman, B. K. Heltsley +64
A golden age for heavy quarkonium physics dawned a decade ago, initiated by the confluence of exciting advances in quantum chromodynamics (QCD) and an explosion of related experime…
Towards the experimental clarification of quarkonium polarization
Pietro Faccioli, Carlos Lourenco, Joao Seixas +1
We highlight issues which are often underestimated in the experimental analyses on quarkonium polarization: the relation between the parameters of the angular distributions and the…
