Multi-instanton and string loop corrections in toroidal orbifold models
P. G. Camara, E. Dudas
We analyze N=2 (perturbative and non-perturbative) corrections to the effective theory in type I orbifold models where a dual heterotic description is available. These corrections…
String instantons, fluxes and moduli stabilization
P. G. Camara, E. Dudas, T. Maillard +1
We analyze a class of dual pairs of heterotic and type I models based on freely-acting orbifolds in four dimensions. Using the adiabatic argument…
Supersymmetric Models with Higher Dimensional Operators
I. Antoniadis, E. Dudas, D. M. Ghilencea
In 4D renormalisable theories, integrating out massive states generates in the low energy effective action higher dimensional operators (derivative or otherwise). Using a superfiel…
Metastable String Vacua
C. Angelantonj, E. Dudas
We argue that tachyon-free type I string vacua with supersymmetry breaking in the open sector at the string scale can be interpreted, via S and T-duality arguments, as metastable v…
Dual realizations of dynamical symmetry breaking
Emilian Dudas, Chloe Papineau
We show the infrared equivalence between a recently proposed model containing a six dimensional scalar field with a four-dimensional localized Higgs type potential and the four-dim…
Moduli stabilization with positive vacuum energy
E. Dudas, Y. Mambrini
We study the effect of anomalous U(1) gauge groups in string theory compactification with fluxes. We find that, in a gauge invariant formulation, consistent AdS vacua appear breaki…
