Today, the model has essentially been absorbed as a component of the established quantum field theory of strong and electroweak particle interactions, dubbed the [[Standard Model]].

Hadrons are not really "elementary", and can be regarded as bound states of their "valence quarks" and antiquarks, which give rise to the [[quantum number]]s of the hadrons. These quantum numbers are labels identifying the hadrons, and are of two kinds. One set comes from the [[Poincaré symmetry]]—''J''^''PC'', where ''J'', ''P'' and ''C'' stand for the [[total angular momentum]], [[P-symmetry]], and [[C-symmetry]], respectively.
