Abstract
We investigate within the framework of the kaon-soliton bound state model of hyperons the effects of introducing a linear combination of possible four-derivative stabilization terms allowed by general symmetry principles. We calculate the mass spectrum and magnetic moments of hyperons and see how they vary as a function of a new mixing parameter x. In all previous bound state model calculations this parameter was fixed at 1. We show that in some cases, a smaller value leads to improvement in the description of hyperon properties. We discuss empirical bounds coming from chiral perturbation theory for the possible values of x as well as the mesonic origin of the term it parametrizes.
