The Character of Goldstone Bosons
Abstract
A succinct review of the QCD gap equation and dynamical chiral symmetry breaking; their connection with Bethe-Salpeter equations and resolving the dichotomous nature of the pion; the calculation of the pion's valence-quark distribution; and first results for the π-exchange contribution to the γN → ωN cross-section, which is important in the search for missing nucleon resonances.
