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…

Computation of D-brane instanton induced superpotential couplings - Majorana masses from string theory
Mirjam Cvetic, Robert Richter, Timo Weigand
We perform a detailed conformal field theory analysis of D2-brane instanton effects in four-dimensional type IIA string vacua with intersecting D6-branes. In particular, we explici…
