Abstract
Techniques for estimating the masses and decay couplings of multiquark hadrons (, ) are developed with specific reference to the sector. The dynamics is based on a quark-bag model of light, colored, and permanently confined quarks gauge-coupled to non-Abelian colored gluons. The SU (6) of "color-spin" generated by color SU (3) and the SU (2) of relativistic quarks dominates the spectrum. Color-spin rules analogous to Hund's rules of atomic spectroscopy dictate that the lightest multiquark handrons are not exotic, are of low spin, and are coupled predominantly to strange and decay channels, Multiquark hadrons are consequently elusive and may be misclassified as conventional mesons or baryons.
