Baryon Spectroscopy and the Constituent Quark Model
arXiv:hep-ph/0510293
Abstract
We explore further the idea that the lattice QCD data for hadron properties in the region m_π^2 > 0.2 GeV^2 can be described by the constituent quark model. This leads to a natural explanation of the fact that nucleon excited states are generally stable for pion masses greater than their physical excitation energies. Finally we apply these same ideas to the problem of how pentaquarks might behave in lattice QCD, with interesting conclusions.
