Moduli Inflation with Large Scale Structure Produced by Topological Defects
Katherine Freese, Tony Gherghetta, Hideyuki Umeda
It is tempting to inflate along one of the many flat directions that arise in supersymmetric theories. The required flatness of the potential to obtain sufficient inflation and to…
Low-Energy Supersymmetry Breaking and Fermion Mass Hierarchies
Tony Gherghetta, Gerard Jungman, Erich Poppitz
In models with low-energy supersymmetry breaking, an anomalous Abelian horizontal gauge symmetry can simultaneously explain the fermion mass hierarchy and the values of the and…
Flat directions in the scalar potential of the supersymmetric standard model
Tony Gherghetta, Chris Kolda, Stephen P. Martin
The scalar potential of the Minimal Supersymmetric Standard Model (MSSM) is nearly flat along many directions in field space. We provide a catalog of the flat directions of the ren…
Chaotic inflation and a radiatively generated intermediate scale in the supersymmetric standard model
Tony Gherghetta, Gordon L. Kane
We consider a phenomenological extension of the minimal supersymmetric standard model which incorporates chaotic inflation and a radiatively generated intermediate mass scale. Init…
