Instanton calculus in R-R background and the topological string
Marco Billo, Marialuisa Frau, Francesco Fucito +1
We study a system of fractional D3 and D(-1) branes in a Ramond-Ramond closed string background and show that it describes the gauge instantons of N=2 super Yang-Mills theory and t…
The partition function of interfaces from the Nambu-Goto effective string theory
M. Billo, M. Caselle, L. Ferro
We consider the Nambu-Goto bosonic string model as a description of the physics of interfaces. By using the standard covariant quantization of the bosonic string, we derive an exac…
Brane world effective actions for D-branes with fluxes
Matteo Bertolini, Marco Billo, Alberto Lerda +2
We develop systematic string techniques to study brane world effective actions for models with magnetized (or equivalently intersecting) D-branes. In particular, we derive the depe…
