We study the D3/D(-1) brane system and show how to compute instanton corrections to correlation functions of gauge theories in four dimensions using open string techniques. In particular we show that the disks with mixed boundary conditions that are typical of the D3/D(-1) system are the sources for the classical instanton solution. This can then be recovered from simple calculations of open string scattering amplitudes in the presence of D-instantons. Exploiting this fact we also relate this stringy description to the standard instanton calculus of field theory.

- Moduli Stabilisation versus Chirality for MSSM like Type IIB Orientifolds (2007, methodology): “It can then be regarded as a gauge instanton from the perspective of the D7-brane gauge theory and additional bosonic and non-chiral fermionic zero modes arise parametrising the ADHM instanton super moduli space [44, 57, 51, 52].”
- d-Brane Instantons in Type II Orientifolds (2009, methodology): “Open string perturbation theory can be used to describe the fluctuations of Ep-branes and an instanton calculus can be defined in analogy to the field theory case [12, 13, 14, 15, 16, 17].”

- Instanton Induced Neutrino Majorana Masses in CFT Orientifolds with MSSM-like spectra (2007, background): “They act as Lagrange multipliers which impose the fermionic constraints in the ADHM construction [28], and may not spoil the generation of a superpotential.”
