Sigma c baryon (${\Sigma }_c^{++,+,0},{\Sigma }_c^{\ast ++,\ast +,\ast 0}$)

The symmetric light pairs $uu,\{ud\},dd$ with one charm quark give isospin one and charges $2,1,0$. Their light spin is one; coupling the charm spin gives the $J=1/2$ Sigma c baryon triplet and $J=3/2$ excited-spin triplet conventionally marked by a star.
