Exotic instanton counting and heterotic/type I' duality
Marco Billo', Livia Ferro, Marialuisa Frau +3
We compute the partition function for the exotic instanton system corresponding to D-instantons on D7 branes in Type I' theory. We exploit the BRST structure of the moduli action a…
Classical solutions for exotic instantons?
Marco Billo', Marialuisa Frau, Laurent Gallot +2
We consider the D7/D(--1) system in Type I' as a prototypical "exotic" brane instanton. With respect to systems such as the D3/D(-1) ones, which correspond to gauge instantons in f…
Superconformal Invariants or How to Relate Four-point AdS Amplitudes
J. M. Drummond, L. Gallot, E. Sokatchev
Using the form of N=2 superconformal invariants we derive the explicit relation between the bottom and top components of the correlator of four stress-tensor multiplets in N=4 Supe…
