Intersecting branes from 7-manifolds with G_2 holonomy

TL;DR

This paper explores intersecting brane configurations derived from explicit G_2 holonomy metrics on 7-manifolds, including a specific example involving a R^3 bundle over a self-dual Einstein space, and discusses the resulting potential after compactification.

Contribution

It provides an explicit example of a G_2 holonomy 7-manifold and analyzes the resulting brane configurations and potentials after compactification.

Findings

Explicit G_2 holonomy 7-manifold example described.

Potential after compactification over twistor space derived.

Intersections of branes from these manifolds analyzed.

Abstract

In this talk I discuss intersecting brane configurations coming from explicit metrics with G_2 holonomy. An example of a 7-manifold which representing a R^3 bundle over a self-dual Einstein space is described and the potential appearing after compactification over the 6-d twistor space is derived.
