(Non-)Anomalous D-brane and O-plane couplings: the normal bundle
arXiv:hep-th/9812149 · doi:10.1016/S0370-2693(99)00164-1
Abstract
The direct string computation of anomalous D-brane and orientifold plane couplings is extended to include the curvature of the normal bundle. The normalization of these terms is fixed unambiguously. New, non-anomalous gravitational couplings are found.
