On Metastable Branes and a New Type of Magnetic Monopole

Abstract

String compactifications with D-branes may exhibit regular magnetic monopole solutions, whose presence does not rely on broken non-abelian gauge symmetry. These stringy monopoles exist on interesting metastable brane configurations, such as anti-D3 branes inside a flux compactification or D5-branes wrapping 2-cycles that are locally stable but globally trivial. In brane realizations of SM-like gauge theories, the monopoles carry one unit of magnetic hypercharge. Their mass can range from the string scale down to the multi-TeV regime.
