We compute the total cross section of a heavy quarkonium on a hadron targetin leading twist QCD, including target mass corrections. Our method relies onthe analytical continuation of the operator product expansion of the scatteringamplitude, obtained long ago by Bhanot and Peskin. The cross section has asimple partonic form, which allows us to investigate the phenomenology of J/psiand Upsilon dissociation by both pions and protons.Comment: 21 pages, 4 figures, REVTeX4.
