Enhanced Symmetries of Orbifolds from Moduli Stabilization
Wilfried Buchmuller, Riccardo Catena, Kai Schmidt-Hoberg
We study a supersymmetric field theory in six dimensions compactified on the orbifold T^2/Z_2 with two Wilson lines. After supersymmetry breaking, the Casimir energy fixes the shap…
Large hierarchies from approximate R symmetries
Rolf Kappl, Hans Peter Nilles, Saul Ramos-Sanchez +3
We show that hierarchically small vacuum expectation values of the superpotential in supersymmetric theories can be a consequence of an approximate R symmetry. We briefly discuss t…
The Gravitino-Stau Scenario after Catalyzed BBN
Joern Kersten, Kai Schmidt-Hoberg
We consider the impact of Catalyzed Big Bang Nucleosynthesis on theories with a gravitino LSP and a charged slepton NLSP. In models where the gravitino to gaugino mass ratio is bou…
