Probing the Short-Range Dynamics in Exclusive Scattering off Polarized Deuteron

Abstract

Employing the polarization degrees of freedom in the deuteron allows to isolate smaller than average inter-nucleon distances in the deuteron. As a result one can identify set of high $Q^2$ reactions off polarized deuteron which are particularly sensitive to the short range dynamics of strong interaction. We concentrate on the studies of several aspects of the short range phenomena. These are the relativistic dynamics of electron--bound-nucleon scattering, color coherence in high $Q^2$ electro-production as well as the formation of the vector mesons in coherent electro-production from the deuteron. We address also the issue of extraction of polarized deep inelastic structure function of the neutron.
