Quarkonium hadron interaction in QCD
arXiv:hep-ph/0107096
Abstract
The analytic continuation of the operator product expansion of the scattering amplitude allows to compute the heavy-quarkonium hadron total cross section. The energy dependence of the Upsilon and Upsilon' cross sections with a proton is discussed.
