Fivebrane instantons and Calabi-Yau fourfolds with flux
arXiv:hep-th/0701287 · doi:10.1088/1126-6708/2007/03/099
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.
