Testing the Scalar Weak Gravity Conjecture in No-scale Supergravity
Emilian Dudas, Tony Gherghetta, Keith A. Olive +1
We explore possible extensions of the Weak Gravity Conjecture (WGC) to scalar field theories. To avoid charged black hole remnants, the WGC requires the existence of a particle wit…
Supergravity Scattering Amplitudes
Emilian Dudas, Tony Gherghetta, Keith A. Olive +1
Supergravity theories with non-minimal Kähler potentials are characterized by a non-trivial field space manifold with corresponding non-trivial kinetic terms. The scattering amplit…
Causality constraints on nonlinear supersymmetry
Quentin Bonnefoy, Gabriele Casagrande, Emilian Dudas
It is well-known that gravitino propagation in standard supergravities is free of any causality problems. However, two issues related to gravitino propagation were recently uncover…
Bare-Bones de Sitter
Iosif Bena, Emilian Dudas, Mariana Graña +2
We compute the supersymmetry-breaking three-form fluxes generated by the addition of anti-D3 branes at the tip of a Klebanov-Strassler throat. These fluxes give rise to nontrivial…
Geometry of orientifold vacua and supersymmetry breaking
Thibaut Coudarchet, Emilian Dudas, Hervé Partouche
Starting from a peculiar orientifold projection proposed long ago by Angelantonj and Cardella, we elaborate on a novel perturbative scenario that involves only D-branes, together w…
Slow and Safe Gravitinos
Emilian Dudas, Marcos A. G. Garcia, Yann Mambrini +3
It has been argued that supergravity models of inflation with vanishing sound speeds, , lead to an unbounded growth in the production rate of gravitinos. We consider several m…
