Predictions from an Anomalous U ( 1 ) Model of Yukawa Hierarchies

  title={Predictions from an Anomalous U ( 1 ) Model of Yukawa Hierarchies},
  author={Nikolaos Irges and St{\'e}phane Lavignac and Pierre Ramond},
We present a supersymmetric standard model with three gauged Abelian symmetries, of a type commonly found in superstrings. One is anomalous, the other two are E6 family symmetries. It has a vacuum in which only these symmetries are broken by stringy effects. It reproduces all observed quark and charged lepton Yukawa hierarchies, and the value of the Weinberg angle. It predicts three massive neutrinos, with mixing that can explain both the small angle MSW effect, and the atmospheric neutrino… CONTINUE READING
