  The deuteron disintegration at high energies and large angles in the
$d(p,2p)n$ reaction, is calculated in kinematical conditions where the dominant
contributions are due to soft rescatterings of the initial and final nucleons,
which accompany the hard $pp$ reaction. The eikonal approximation, which
accounts for relativistic kinematics as dictated by Feynman diagrams, reveals
the important role played by the initial and final state interactions in the
angular and momentum dependences of the differential cross section. Based on
these results, we propose a new and effective test, at moderate energies, of
the physics relevant for the color transparency phenomenon in hadron-initiated
exclusive hard processes.
