Anomalous U(1) and low-energy physics: the power of D-flatness and holomorphy
P. Binetruy, N. Irges, S. Lavignac +1
In models with an anomalous abelian symmetry broken at a very large scale, we study which requirements to impose on the anomalous charges in order to prevent standard model fields…
Quasi-degenerate neutrinos from an abelian family symmetry
P. Binetruy, S. Lavignac, S. Petcov +1
We show that models with an abelian family symmetry which accounts for the observed hierarchies of masses and mixings in the quark sector may also accomodate quasi-degeneracies in…
Raising the unification scale in supersymmetry
Stephen P. Martin, Pierre Ramond
In the minimal supersymmetric standard model, the three gauge couplings appear to unify at a mass scale near GeV. We investigate the possibility that intermediat…
Superstrings:The View from Below
P. Ramond
We review the Standard Model in a form conducive to formulating its possible short distance extensions. This depends on the value of the Higgs mass, the only unknown parameter of t…
Sparticle Spectrum Constraints
Stephen P. Martin, Pierre Ramond
The supersymmetric standard model with supergravity-inspired soft breaking terms predicts a rich pectrum of sparticles to be discovered at the SSC, LHC and NLC. Because there are m…
