Abstract
We explore the role of final-state interactions (FSIs) in inclusive deep-inelastic scattering from the deuteron. Relating the inclusive cross section to the deuteron forward virtual Compton scattering amplitude, a general formula for the FSI contribution is derived in the generalized eikonal approximation, utilizing the diffractive nature of the effective hadron-nucleon interaction. The calculation uses a factorized model with a basis of three resonances with mass GeV and a continuum contribution for larger as the relevant set of effective hadron states entering the final-state interaction amplitude. The results show sizeable on-shell FSI contributions for Bjorken and GeV, increasing in magnitude for lower , but vanishing in the high- limit because of phase-space constraints. The off-shell rescattering contributes at and is taken as an uncertainty on the on-shell result.
