W. Lerche, S. Stieberger
TL;DR
This paper reviews the interactions of specific Kodaira 7-planes formed by non-local (p,q) 7-branes, focusing on local and global effects, including moduli-dependent terms and torsion D-brane charges.
Contribution
It introduces methods to compute moduli-dependent terms in the effective action related to Kodaira 7-planes and explores their local and global interaction aspects.
Findings
Computed moduli-dependent terms in the effective action.
Analyzed local Chern-Simons terms on world-volumes.
Explored global interaction effects related to torsion D-brane charges.
Abstract
We review interactions between certain 7-planes which are composed out of mutually non-local (p,q) 7-branes and which correspond to specific Kodaira singularities. We discuss in particular how to compute certain moduli-dependent terms in the effective action. These do not only probe the local Chern-Simons terms on the world-volumina, but also certain global aspects of plane interactions that can be attributed to ``torsion'' (or \ZZ_N-valued) D-brane charges.
