Supersymmetry and Inflation
Lisa Randall
Inflation is a promising solution to many problems of the standard Big-Bang cosmology. Nevertheless, inflationary models have proved less compelling. In this chapter, we discuss wh…
New Mechanisms of Gauge-Mediated Supersymmetry Breaking
Lisa Randall
We review the motivation for Gauge-Mediated Supersymmetry Breaking and discuss some recent advances.
Models of Dynamical Supersymmetry Breaking
Lisa Randall
We review a class of models of dynamical supersymmetry breaking, and give a unified description of these models.
Supernatural Inflation
Lisa Randall, Marin Soljacic, Alan Guth
Most models of inflation have small parameters, either to guarantee sufficient inflation or the correct magnitude of the density perturbations. In this paper we show that, in super…
The Doublet-Triplet Splitting Problem and Higgses as Pseudogoldstone Bosons
Lisa Randall, Csaba Csa'ki
The doublet-triplet splitting problem is probably the most significant challenge to supersymmetric GUT theories. In this talk, we review potential solutions and their problematic a…
Flat Directions and Baryogenesis in Supersymmetric Theories
Lisa Randall
Flat directions are a generic feature of supersymmetric theories. They are of cosmological interest because they can lead to coherent production of scalars. In the early universe s…
