Abstract

Pole dominance in the complex angular momentum plane is used in order to estimate deviations from a perturbative scheme based on the Gell-Mann-Oakes-Renner model of chiral symmetry breaking. It is seen that the deviation can be very large, leading to a mass pattern which corresponds to almost-conserved SU(2)×SU(2), even when the Hamiltonian originally deviates considerably from this limit.
