Intersecting branes in pp-wave spacetime

TL;DR

This paper derives intersecting brane solutions in pp-wave spacetime, providing explicit supergravity solutions, intersection rules, and generalizations to non-extremal cases, all asymptotic to BFHP plane waves without regular horizons.

Contribution

It presents the first explicit supergravity solutions for intersecting branes in pp-wave backgrounds, including non-extremal cases, with detailed intersection rules.

Findings

Solutions are asymptotic to BFHP plane waves.

No regular horizons are present in these solutions.

Both extremal and non-extremal solutions are constructed.

Abstract

We derive intersecting brane solutions in pp-wave spacetime by solving the supergravity field equations explicitly. The general intersection rules are presented. We also generalize the construction to the non-extremal solutions. Both the extremal and non-extremal solutions presented here are asymptotic to BFHP plane waves. We find that these solutions do not have regular horizons.
