Coherent Nuclear Diffractive Production Of Minijets - Illuminating Color Transparency

The cross section for coherent nuclear processes in which an incident meson or photon dissociates diffractively into two jets of high relative transverse momentum (between about 1 and 3 GeV/c) is found to be proportional in QCD to A2 in a wide kinematical region. The leading correction to this is a significant positive term is-proportional-to A7/3 caused by nuclear multiple scattering. We find also that shadowing of hard diffractive processes reappears as a leading twist effect in the TeV energy range.
