Abstract
We study the isospin-changing component of the total second-order radiative-correction operator in a special class of unified gauge theories, with strong interactions taken into account to all orders, and show that the contribution of the weak interactions amounts only to providing an effective cutoff to the electromagnetic contribution.Keywords
