A string theoretic model of gauge mediated supersymmetry beaking
Mirjam Cvetic, Timo Weigand
We propose a robust supergravity model of dynamical supersymmetry breaking and gauge mediation, and a natural embedding in non-perturbative string theory with D-branes. A chiral fi…

D-brane instanton effects in Type II orientifolds: local and global issues
Mirjam Cvetic, Robert Richter, Timo Weigand
We review how D-brane instantons can generate open string couplings of stringy hierarchy in the superpotential which violate global abelian symmetries and are therefore perturbativ…

Hierarchies from D-brane instantons in globally defined Calabi-Yau Orientifolds
Mirjam Cvetic, Timo Weigand
We construct the first globally consistent semi-realistic Type I string vacua on an elliptically fibered manifold where the zero modes of the Euclidean D1-instanton sector allow fo…
