Flux-induced isometry gauging in heterotic strings Original Research Article

We study the effect of flux-induced isometry gauging of the scalar manifold in image heterotic string compactification with gauge fluxes. We show that a vanishing theorem by Witten provides the protection mechanism. The other ungauged isometries in hyper-moduli space could also be protected, depending on the gauge bundle structure. We also discuss the related issue in IIB setting.
