A Relativistic Approach to Deep Inelastic Scattering on the Deuteron

A covariant field theoretical approach to deep inelastic scattering on the deuteron is presented. The deuteron structure function is calculated in terms of the Bethe-Salpeter amplitude. Numerical calculations for the nucleon contribution are made with a realistic model of the $NN$-interaction, including $\pi$-, $\rho$-, $\omega$-, $\eta$-, $\delta$- and $\sigma$-mesons, and results are compared with previous non-relativistic calculations.
