Shedding light on quarkonium formation by producing a photon in association
arXiv:hep-ph/9212256 · doi:10.1103/PhysRevLett.70.1747
Abstract
The process AB --> Quarkonium + photon + X, for a heavy quarkonium state such as J/psi or Upsilon, is considered. The ratio of the cross-sections for this process in pp and pp(bar) collisions is shown to be a vary sensitive probe of models of quarkonium formation.
