Abstract
Nucleon structure functions, as measured in deep-inelastic lepton scat tering, are studied within a covariant scalar diquark spectator model. Regarding the nucleon as an approximate two-body bound state of a qua rk and diquark, the Bethe-Salpeter equation (BSE) for the bound state vertex function is solved in the ladder approximation. The valence qua rk distribution is discussed in terms of the solutions of the BSE.
