Abstract
The phenomenology of quantum-chromodynamics-based constituent quark models is employed to discuss isospin-violating mass differences and mixing angles which can arise from an intrinsic mass difference between down and up quarks. Such effects appear not only directly from the quark mass difference but also indirectly via isospin violations induced by this mass difference in the strong interactions and tend to be much larger than electromagnetic effects.
