Description
We demonstrate that paradigm shift from considering the deuteron as a system of a bound proton and neutron to considering it as a pseudovector composite system from which one observes emerging proton and neutron results in the possibility of probing a new “incomplete” P-statelike structure on the light front (LF). This occurs at large internal momenta, which can be probed in a high energy transfer electro-disintegration of the deuteron. Investigating the deuteron on the light front, where the vacuum fluctuations are suppressed, we found that this new structure can exist only if the deuteron contains non-nucleonic components in its ground state. We investigate the implication of this new state on polarization properties of the deuteron and demonstrate that it will result in in a strong enhancement of the tensor polarization strength of the deuteron beyond the S- and D- state predictions at large internal momenta.
