On Branes and Oriented B-fields

TL;DR

This paper reviews and explores new theories on branes induced by orienting B fields, analyzing their origins from M-theory with G-fluxes, and examining effects like pinning near singularities and brane-antibrane dynamics.

Contribution

It introduces a unified M-theory framework for various brane theories with oriented B fields and explores new examples and effects such as pinning and flux configurations.

Findings

Brane theories with oriented B fields can be derived from M-theory G-flux limits.

Pinning effects of branes near conifold singularities are characterized.

Different fluxes lead to diverse brane-antibrane dynamics.

Abstract

Novel theories appear on the world-volume of branes by orienting B fields along various directions of the branes. We review some of the earlier developments and explore many new examples of these theories. In particular, among other things, we study the pinning effect of branes near conifold like singularities and brane-antibrane theories with different fluxes on their world-volumes. We show that all these theories arise from different limits of an M-theory configuration with appropriately chosen G-fluxes. This gives us a way to study them from a unified framework in M-theory.
