R-Parity-violating supersymmetry

- R. Barbier, C. Bérat, +9 authors Y. Sirois
- Physics
- 1 November 2005

Theoretical and phenomenological implications of R-parity violation in supersymmetric theories are discussed in the context of particle physics and cosmology. Fundamental aspects include the relation… Expand

On hypercharge flux and exotics in F-theory GUTs

- E. Dudas, Eran Palti
- Physics
- 8 July 2010

We study SU(5) Grand Unified Theories within a local framework in F-theory with multiple extra U(1) symmetries arising from a small monodromy group. The use of hypercharge flux for doublet-triplet… Expand

Gauge couplings in four-dimensional Type I string orbifolds

- I. Antoniadis, C. Bachas, E. Dudas
- Physics
- 4 June 1999

We compute threshold effects to gauge couplings in four-dimensional ZN orientifold models of type I strings with N = 2 and N = 1 supersymmetry, and study their dependence on the geometric moduli. We… Expand

The Volkov–Akulov–Starobinsky supergravity

- I. Antoniadis, E. Dudas, S. Ferrara, A. Sagnotti
- Physics
- 13 March 2014

Abstract We construct a supergravity model whose scalar degrees of freedom arise from a chiral superfield and are solely a scalaron and an axion that is very heavy during the inflationary phase. The… Expand

Supersymmetry breaking

- E. Dudas
- 2009

We review the various mechanisms of supersymmetry breaking and its transmission to the observable sector. We argue that hybrid models where gauge dominates over gravity mediation, but gravity… Expand

Type-I strings on magnetised orbifolds and brane transmutation

- C. Angelantonj, I. Antoniadis, E. Dudas, A. Sagnotti
- Physics
- 11 July 2000

Abstract In the presence of internal magnetic fields, a D9 brane can acquire a D5 (or anti-D5) R-R charge, and can therefore contribute to the corresponding tadpole. In the resulting vacua,… Expand

Strong moduli stabilization and phenomenology

- E. Dudas, Andrei Linde, Y. Mambrini, A. Mustafayev, K. Olive
- Physics
- 3 September 2012

We describe the resulting phenomenology of string theory/supergravity models with strong moduli stabilization. The KL model with F-term uplifting, is one such example. Models of this type predict… Expand

Froggatt-Nielsen models from E8 in F-theory GUTs

- E. Dudas, Eran Palti
- Physics
- 4 December 2009

This paper studies F-theory SU(5) GUT models where the three generations of the standard model come from three different curves. All the matter is taken to come from curves intersecting at a point of… Expand

Uplifting Runaways.

- I. Bena, E. Dudas, M. Graña, Severin Lust
- Physics
- 18 September 2018

We find a mechanism by which antibranes placed in a warped deformed conifold throat can destroy the stabilization of the size of the sphere at the tip, collapsing it to zero size. This conifold… Expand

Brane solutions in strings with broken supersymmetry and dilaton tadpoles

Abstract The tachyon-free nonsupersymmetric string theories in ten dimensions have dilaton tadpoles which forbid a Minkowski vacuum. We determine the maximally symmetric backgrounds for the USp (32)… Expand
