Maths HEP Lunchtime Seminars: Conifold Geometries and NS5-branes

Presented by Jock McOrist, Cambridge

14 October 2011 13:00 in CM221

I will describe a how to construct the near horizon supergravity solution for a pair of NS5-branes, intersecting on R^{1,3} and localised in all directions except a single transverse circle. Such solutions are exceedingly rare, and yet have applications in gauge-gravity duality and model building. The construction makes use of an explicit map between the conifold metric and the near horizon geometry of two intersecting NS5-branes, clarifying and correcting a number of open issues en route. I will also describe additional intersecting brane solutions corresponding to, for example, separating the NS5-branes.
