Field theory interpretation of mathcal{N} = 2 stringy instantons
Abstract
We consider stringy instanton contributions to the prepotential of low-energy mathcal{N} =2theoriesengineeredbyD-branesetupsatorbifoldandorientifoldsingularities. We show that such contributions can always be reproduced in a purely field theoretic UV completion. We perform the explicit check up to instanton number three, both for Sp(0) and U(1) stringy instantons, the latter being introduced for the purpose. We further argue that the UV completion that we propose, though weakly coupled, can be smoothly mapped to a gravity-dual inspired UV completion consisting of a cascade of baryonic root transitions.
