QCD rescattering and high energy two-body photodisintegration of the deuteron

Photon absorption by a quark in one nucleon followed by its high momentum t ransfer interaction with a quark in the other may produce two nucleons with high relative momentum. We sum the relevant quark rescattering diagrams, t o show that the scattering amplitude depends on a convolution between the l arge angle pn scattering amplitude, the hard photon-quark interaction verte x and the low-momentum deuteron wave function. The computed cross sections are in reasonable agreement with the data.
