Supersymmetries in the early universe
Abstract/Contents
- Abstract
- This thesis studies the role of supersymmetry in early universe physics, with emphasis on dark matter phenomenology and cosmic inflation. Motivated by observational anomalies, the first half of the thesis proposes a new class of dark matter: composite nearly supersymmetric dark matter. To establish the constraints imposed by supersymmetry on non-relativistic bound states, a supersymmetric version of the hydrogen atom is studied in detail, and general features are emphasized. After discussing supersymmetry breaking and the interactions of supersymmetric bound states, a dark matter model, where interactions with the Standard Model communicate supersymmetry breaking, is developed. The second part of the thesis develops a class of single field inflation models within the framework of supergravity, which allows for functional freedom in choosing the shape of the potential. A relationship between inflaton stability and the Kähler potential is established. This model is then extended to include the matter fields of the visible sector, and supersymmetry breaking is induced using a phenomenological version of the KKLT model. Finally, reheating, and a solution of the cosmological moduli and graviton problem, are discussed.
