Description

In order to allow for a large ππ scattering length a₀⁽⁰⁾, a reducible model of chiral-symmetry breaking is considered. Our model yields reasonable possible values for the width of the decay η′→nππ. A sum rule connecting chiral and dilatational symmetry breaking is furthermore fulfilled in the model.
