Coherent Nuclear Diffractive Production of Minijets - Illuminating Color Transparency
L. Frankfurt, G. A. Miller, M. Strikman
Abstract
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 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.
