Abstract

In an SUL(2)-Higgs model with one chirally coupled flavor, fermioniz zero modes are constructed in the background of an instanton when there is no custodial global SU(2) symmetry to ensure degenerate fermion masses. The generalization to more fermion flavors and colors is straightforward.
