= Baryons with one isospin-singlet quark
{title2=$Q(h[ud])=q_h+1/3$}
For an <isospin> singlet <quark> $h$ of charge $q_h$, the antisymmetric light-flavour pair gives an $I=0,J=1/2$ state with charge $q_h+1/3$. The symmetric light-flavour pairs $uu,\{ud\},dd$ give $I=1$ triplets of spins $1/2$ and $3/2$, with charges $q_h+4/3,q_h+1/3,q_h-2/3$. These follow from <light-diquark spin-isospin correlation> and addition of constituent <electric charges>, with zero <orbital angular momentum>.
