Confinement 2 : phenomenology in the MIT bag

It is shown that the MIT bag model provides a specific framework in which to do calculations with confined quarks. The spectrum of the low lying hadrons and the static properties are in good agreement with data. The model predicts the existence of multiquark states and glueballs and enables specific prediction for the quark transverse momentum to be made. As well as giving a valence distribution for the parton distribution it also predicts the existence of a sea term, even without gluons. (U.K.)
