Vacua with Small Flux Superpotential

Abstract

We describe a method for finding flux vacua of type IIB string theory in which the Gukov-Vafa-Witten superpotential is exponentially small. We present an example with ${W}_{0}\ensuremath{\approx}2\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}8}$ on an orientifold of a Calabi-Yau hypersurface with $({h}^{1,1},{h}^{2,1})=(2,272)$, at large complex structure and weak string coupling.
