Yukawa Textures and Anomalies

Abstract

We augment the Minimal Supersymmetric Standard Model with a gauged family-dependent to reproduce Yukawa textures compatible with experiment. In the simplest model with one extra chiral electroweak singlet field, acceptable textures require this to be anomalous. The cancellation of its anomalies by a generic Green-Schwarz mechanism requires at the string scale, suggesting a superstring origin for the standard model.
