A symmetry-preserving treatment of a vector  ×  vector contact interaction is used to compute spectra of ground-state J P = 0 ± , 1 ± ( f g ¯ ) mesons, their partner diquark correlations, and J P = 1 / 2 ± , 3 / 2 ± ( fg h ) baryons, where f , g , h ∈ { u , d , s , c , b } . Results for the leptonic...
