Chiral Symmetry Realization in the Quark Model

Chiral symmetry realizations of the quark-gluon model are considered in the absence of self-energy insertions for the gluon and photon, so the bare fermion mass vanishes. We exhibit the conditions which realize the chiral symmetry with Nambu-Goldstone bosons as bound states. A formal argument indicates that in this model electromagnetic corrections to the strong interactions are then finite to leading order and possibly all orders.
