TL;DR

This paper constructs new M-brane solutions in M-theory using Gibbons-Hawking spaces, leading to fully localized brane intersections with novel metric dependencies and revealing new six-dimensional little string theories.

Contribution

It introduces M2 and M5-brane solutions based on Gibbons-Hawking spaces with metric functions depending on multiple transverse coordinates, expanding the landscape of known supergravity solutions.

Findings

Solutions preserve eight supersymmetries

Realize fully localized D2/D6 and NS5/D6 intersections

Identify new non-local, non-gravitational six-dimensional theories

Abstract

We present new M2 and M5-brane solutions in M-theory based on transverse Gibbons-Hawking spaces. These solutions provide realizations of fully localized type IIA D2/D6 and NS5/D6 brane intersections. One novel feature of these solutions is that the metric functions depend on more than two transverse coordinates (unlike all the other previous known solutions). All the solutions have eight preserved supersymmetries and the world-volume theories of the NS5-branes are new non-local, non-gravitational, six dimensional, T-dual little string theories with eight supersymmetries. We discuss the limits in which the dynamics of the D2 and NS5-branes decouple from the bulk for these solutions.
