摘要：

A symmetry-preserving truncation of the strong-interaction bound-state equations is used to calculate the spectrum of ground-state J=1/2+, 3/2+(qqq)-baryons, where q,q,q{u,d,s,c,b}, their first positive-parity excitations and parity partners. Using two parameters, a description of the known spectrum of 39 such states is obtained, with a mean-absolute-relative-difference between calculation and experiment of 3.6(2.7)%. From this foundation, the framework is subsequently used to predict the masses of 90 states not yet seen empirically.
