Fivebrane instantons and Calabi-Yau fourfolds with flux

High Energy Physics - Theory 2009-11-13 v2

Abstract

Using recent results on eleven-dimensional superspace, we compute the contribution of fivebrane instantons with four fermionic zeromodes in M-theory compactifications on Calabi-Yau fourfolds with flux. We find that no superpotential is generated in this case. This result is compatible with a certain flux-dependent modification of the arithmetic genus criterion.
