Abstract
We present a class of supersymmetric models in which flavor symmetries are broken dynamically, by a set of composite haven fields. The stron g dynamics that is responsible for confinement in the flavor sector al so drives flavor symmetry-breaking vacuum expectation values, as a con sequence of a quantum-deformed moduli space. Yukawa couplings result a s a power series in the ratio of the confinement to Planck scale, and the fermion mass hierarchy depends on the differing number of preens i n different flavor symmetry-breaking operators. We present viable non- Abelian and Abelian flavor models that incorporate this mechanism. [S0 556-2821(97)01923-1].
