Description

Scattering reactions on the deuteron, being spin 1 and having tensor polarization modes, involve more independent structures than those on the nucleon. I discuss aspects of the tensor polarized asymmetry Azz in deep inelastic scattering on the deuteron. In light of the upcoming JLab measurements I focus on and discuss the contributions of leading and higher-twist contributions to the asymmetry. I also demonstrate how tagging a spectator nucleon allows to measure maximal Azz (1,-2) asymmetries and provides constraints on the deuteron nuclear structure, in contrast to the inclusive values which are tiny. These measurements would be possible with the far-forward detecors at the EIC when operating with polarized deuteron beams.
