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…

Enlarging mSUGRA parameter space by decreasing pre-BBN Hubble rate in Scalar-Tensor Cosmologies
R. Catena, N. Fornengo, A. Masiero +2
We determine under what conditions Scalar Tensor cosmologies predict an expansion rate which is reduced as compared to the standard General Relativity case. We show that ST theorie…

Aspects of a supersymmetric Brans-Dicke theory
Riccardo Catena
We consider a locally supersymmetric theory where the Planck mass is replaced by a dynamical superfield. This model can be thought of as the Minimal Supersymmetric extension of the…
