Intersecting Brane Vacua and Non-perturbative Transitions
arXiv:1203.0172
Abstract
We discuss the process of transmutation of branes into Abelian magnetic flux on the worldvolume of branes. This phenomenon is T-dual to the recombination of branes in the intersecting-brane description. In the low energy limit this can be described by a Higgs mechanism involving bifundamental scalars. The Abelian magnetic background arises as a consequence of the compactness of the internal space. Explicit (six-dimensional) examples based on the supersymmetric and the Brane Supersymmetry Breaking (BSB) \mathbb{T}^4/\mathbb{Z}_2 orientifold are analyzed.
