Intersections of S-branes with Waves and Monopoles

TL;DR

This paper explores how S-branes can intersect with waves and monopoles in string theory, revealing unique configurations and limitations, especially regarding adding waves and S-branes to certain p-brane intersections.

Contribution

It systematically constructs S-brane intersections with waves and monopoles, highlighting differences from p-branes and identifying constraints on such configurations.

Findings

Monopoles can be added to S-branes similarly to p-branes.

Waves can only be added to the transverse space of S-branes.

Adding an S-brane to certain p-brane intersections with AdS geometry is not possible.

Abstract

We construct intersections of S-branes with waves and Kaluza-Klein monopoles. There are several possible ways to add a monopole to an S-brane solution similar to p-branes. On the other hand, one may add a wave only to the transverse space of an S-brane unlike a p-brane where wave resides on its worldvolume. The metric function of the wave is a harmonic function of the remaining transverse directions and an extra condition on integration constants is needed. We also show that it is not possible to add an S-brane to p-brane intersections whose near horizon geometry has an AdS part.
