Description

The deuteron, the most fundamental nuclear system, has a wave function predominantly characterized by the proton-neutron ($pn$) component. As such, it serves as a valuable tool for probing various aspects of the $pn$ strong interaction. Studying the $pn$ system at short distances addresses fundamental questions in nuclear dynamics, such as the relativistic description of nuclear structure, the dynamics of the repulsive core in nucleon-nucleon ($NN$) interactions, the role of non-nucleonic degrees of freedom, and the transitions between hadrons and quarks at very short distances. Utilizing a tensor-polarized deuteron target in electro-production reactions opens up new possibilities for exploring phenomena in short-range hadronic and nuclear physics. Additionally, $pn$ potentials like AV18 and CD-Bonn show significant differences in their high-momentum projections, which correspond to small inter-nucleon distances. Theoretical studies suggest that these differences could be identified and measured through specialized electro-disintegration experiments involving a tensor-polarized target.
