Amir-Kian Kashani-Poor, Alessandro Tomasiello
TL;DR
This paper shows how fluxes in string theory protect certain isometries from quantum corrections, aligning supergravity predictions with quantum effects, and clarifies which isometries remain or are broken.
Contribution
It demonstrates that fluxes safeguard specific isometries from quantum breaking, confirming supergravity predictions and clarifying the fate of other isometries.
Findings
Fluxes protect gauged isometries from quantum corrections.
Most other isometries are broken by quantum effects.
Supergravity analysis aligns with quantum behavior of isometries.
Abstract
Supergravity analysis suggests that the effect of fluxes in string theory compactifications is to gauge isometries of the scalar manifold. However, isometries are generically broken by brane instanton effects. Here we demonstrate how fluxes protect exactly those isometries from quantum corrections which are gauged according to the classical supergravity analysis. We also argue that all other isometries are generically broken.
