Non-perturbative F-terms across lines of BPS stability
Inaki Garcia-Etxebarria, Fernando Marchesano, Angel M. Uranga
We consider non-perturbative terms in the 4d effective action due to BPS D-brane instantons, and study their continuity properties in moduli space as instantons cross lines of BPS…
E3-brane instantons and baryonic operators for D3-branes on toric singularities
Davide Forcella, Inaki Garcia-Etxebarria, Angel Uranga
We consider the couplings induced on the world-volume field theory of D3-branes at local toric Calabi-Yau singularities by euclidean D3-brane (E3-brane) instantons wrapped on (non-…
Non-perturbative superpotentials across lines of marginal stability
Inaki Garcia-Etxebarria, Angel M. Uranga
We discuss the behaviour of non-perturbative superpotentials in 4d N=1 type II compactifications (and orientifolds thereof) near lines of marginal stability, where the spectrum of…
Supersymmetry breaking metastable vacua in runaway quiver gauge theories
Inaki Garcia-Etxebarria, Fouad Saad, Angel M. Uranga
In this paper we consider quiver gauge theories with fractional branes whose infrared dynamics removes the classical supersymmetric vacua (DSB branes). We show that addition of fla…
Non-supersymmetric Meta-stable Vacua from Brane Configurations
Sebastian Franco, Inaki Garcia-Etxebarria, Angel M. Uranga
We construct configurations of NS-, D4-, and D6-branes in type IIA string theory, realizing the recently discussed non-supersymmetric meta-stable minimum of 4d N=1 SU(N_c) super-Ya…
Local models of Gauge Mediated Supersymmetry Breaking in String Theory
Inaki Garcia-Etxebarria, Fouad Saad, Angel M. Uranga
We describe local Calabi-Yau geometries with two isolated singularities at which systems of D3- and D7-branes are located, leading to chiral sectors corresponding to a semi-realist…
