Final-state interactions in deep-inelastic scattering from a tensor polarized deuteron target

Understand

Deep-inelastic scattering (DIS) from a tensor polarized deuteron is sensitive to possible non-nucleonic components of the deuteron wave function.

• To accurately estimate the size of the nucleonic contribution, final-state interactions (FSIs) need to be accounted for in calculations.
• We outline a model that, based on the diffractive nature of the effective hadron-nucleon interaction, uses the generalized eikonal approximation to model the FSIs in the resonance region, taking into account the proton-neutron component of the deuteron.
• The calculation uses a factorized model with a basis of three resonances with mass $W<2$ GeV as the relevant set of effective hadron states entering the final-state interaction amplitude for inclusive DIS.
