Exotic hadron

Exotic hadrons are subatomic particles composed of quarks and gluons, but which do not have the same quark content as ordinary hadrons: exotic baryons differ from the three-quark (qqq) content of ordinary baryons, and exotic mesons differ from the quark-antiquark (q) content of ordinary mesons.

Total angular momentum quantum number

In quantum mechanics, the total angular momentum quantum number parameterises the total angular momentum of a given particle, by combining its orbital angular momentum and its intrinsic angular momentum (i.e., its spin).
