N=2 Supersymmetric Theories, Dyonic Charges and Instantons (2007)
This paper contains the results of our investigations of BPS instantons and of our work on N=2 supersymmetric gauge theories. The BPS instantons we study appear in type II string theory...
Lagrangians with electric and magnetic charges of N=2 supersymmetric gauge theories (2007)
De Vroome, Mathijs, De Wit, Bernard
General Lagrangians are constructed for N=2 supersymmetric gauge theories in four space-time dimensions involving gauge groups with (non-abelian) electric and magnetic charges. The charges induce a...
Supergravity description of spacetime instantons (2006)
De Vroome, Mathijs, Vandoren, Stefan
We present and discuss BPS instanton solutions that appear in type II string theory compactifications on Calabi-Yau threefolds. From an effective action point of view these arise as finite action...
