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…
Instanton Induced Open String Superpotentials and Branes at Singularities
L. E. Ibanez, A. M. Uranga
We study different aspects of the non-perturbative superpotentials induced by Euclidean E3-branes on systems of D3/D7-branes located at Abelian orbifold singularities. We discuss i…
Instanton Induced Neutrino Majorana Masses in CFT Orientifolds with MSSM-like spectra
L. E. Ibanez, A. N. Schellekens, A. M. Uranga
Recently it has been shown that string instanton effects may give rise to neutrino Majorana masses in certain classes of semi-realistic string compactifications. In this paper we m…
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…
