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 final-state n ucleons with high relative momentum. We sum the relevant quark rescattering diagrams to show that the scattering amplitude depends on a convolution be tween the large angle pn scattering amplitude, the hard photon-quark intera ction vertex, and the low-momentum deuteron wave function. The computed abs olute values of the cross section are in reasonable agreement with the data .
