D-Instanton Corrections as (p,q)-String Effects and Non-Renormalization Theorems
Alexandros Kehagias, Herve Partouche
We discuss higher derivative interactions in the type IIB superstring in ten dimensions. From the fundamental string point of view, the non-perturbative corrections are due to D-in…

On the exact quartic effective action for the type IIB superstring
A. Kehagias, H. Partouche
We propose a four-point effective action for the graviton, antisymmetric two-forms, dilaton and axion of type IIB superstring in ten dimensions. It is explicitly SL(2,Z)-invariant…

On the Ground State of the Supersymmetric Five-brane
Alexandros Kehagias
We examine if there exists a zero-energy supersymmetric ground state for the fundamental five-brane. Looking for an - invariant ground state, we construct, in th…
