摘要：We compute the vector-meson, nucleon and Δ=Ω-baryon masses and their evolution with the current-quark mass using a covariant generalized Bethe-Salpeter equation approach. The inter- action kernel is truncated to a dressed gluon exchange. We study the model dependence of our results with the quark-gluon dressing to assess the validity of the truncation.
