Non-perturbative gauge couplings from holography
arXiv:1201.4231 · doi:10.1002/prop.201200007
Abstract
We show how D-instanton corrections modify the dilaton-axion profile emitted by an O7/D7 system turning it into the non-singular F-theory background which corresponds to the effective coupling on a D3 probe.
