Title: Exotic hadrons in the constituent quark model.

Abstract

Exotic hadrons are important because their existence or absence can provide important clues to understanding how QCD makes hadrons from quarks and gluons. The first experimentally confirmed exotic will be the first hadron containing both qq and {bar q}q pairs and the first hadron containing color sextet and color octet pairs. Theoretical models are not very useful because there is no accepted model for multiquark systems with color-space correlations. The constituent quark model is the only phenomenological model with predictive power that has given experimentally tested universal predictions for both mesons and baryons. This paper reviews its explanation for why there are no bound exotics and its guidance to the search for heavy-flavored exotic tetraquarks and pentaquarks. A possible supersymmetry between mesons and baryons leading to meson-baryon mass relations not easily obtained otherwise is discussed.
