We determine the baryon octet and decuplet masses as well as their wavefunctions in a covariant three-body Faddeev approach. We work in anapproximation where irreducible three-body forces are neglected. In thetwo-body interactions we take into account a well explored rainbow-ladderkernel as well as flavor dependent meson-exchange terms motivated from theunderlying quark-gluon interaction. Without flavor dependent forces we findagreement with the experimental spectrum on the 5-10 percent level. Includingthe flavor dependent terms on an exploratory level delivers a Sigma/Lambdasplitting with the correct sign although the magnitude is still too small.
