Gravitino Dark Matter
Wilfried Buchmuller
Gravitino dark matter, together with thermal leptogenesis, implies an upper bound on the masses of superparticles. In the case of broken R-parity the constraints from primordial nu…
Light Moduli in Almost No-Scale Models
Wilfried Buchmuller, Jan Moller, Jonas Schmidt
We discuss the stabilization of the compact dimension for a class of five-dimensional orbifold supergravity models. Supersymmetry is broken by the superpotential on a boundary. Cla…
Probing Gravitino Dark Matter with PAMELA and Fermi
Wilfried Buchmüller, Alejandro Ibarra, Tetsuo Shindou +2
We analyze the cosmic-ray signatures of decaying gravitino dark matter in a model independent way based on an operator analysis. Thermal leptogenesis and universal boundary conditi…
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…
