Quarkonium hadron interaction in QCD

4 pages, 2 figures. Talk given at XXXVIth Rencontres de Moriond: QCD and High Energy Hadronic Interactions, Les Arcs, France, 17-24 March 2001The 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
