Non-perturbative effective interactions from fluxes
M. Billo', L. Ferro, M. Frau +3
Motivated by possible implications on the problem of moduli stabilization and other phenomenological aspects, we study D-brane instanton effects in flux compactifications. We focus…

Flux interactions on D-branes and instantons
Marco Billo', Livia Ferro, Marialuisa Frau +3
We provide a direct world-sheet derivation of the couplings of NS-NS and R-R fluxes to various types of D-branes (including instantonic ones) by evaluating disk amplitudes among tw…
