摘要：

First and second order QCD contributions are calculated for the process μN → μψX. Striking signature differences compel the identification of O(αs) QCD with diffractive and O(αs2) QCD with non-diffractive scattering: the O(αs) cross section peaks sharply at t = 0, and has large positive ψ rapidity and little hadronic energy recoil; the O(αs2) cross section has a flat t dependence, small ψ rapidity and large hadronic energy recoil. © 1979.
