    "abstract": "We treat baryons as bound states of scalar or axialvector diquarks and a\nconstituent quark which interact through quark exchange. This description\nresults as an approximation to the relativistic Faddeev equation for three\nquarks which yields an effective Bethe-Salpeter equation. Octet and decuplet\nmasses and fully four-dimensional wave functions have been computed for two\ncases: assuming an essentially pointlike diquark on the one hand, and a diquark\nwith internal structure on the other hand. Whereas the differences in the mass\nspectrum are fairly small, the nucleon electromagnetic form factors are greatly\nimproved assuming a diquark with structure. First calculations to the\npion-nucleon form factor also suggest improvements.",
