Brane World in a Topological Black Holes in Asymptotically Flat Spacetime

TL;DR

This paper explores static brane configurations in topological black hole backgrounds within asymptotically flat spacetime, highlighting differences from AdS black holes and constructing a brane world model with an orbifold structure.

Contribution

It demonstrates the existence of static brane configurations in flat black hole backgrounds and develops a brane world model with an orbifold in this setting.

Findings

Static brane configurations are possible in flat black hole backgrounds.

Constructed a brane world model with S^1/Z_2 orbifold structure.

Studied behavior of massless bulk scalar fields in this context.

Abstract

We study static brane configurations in the bulk background of the topological black holes in asymptotically flat spacetime. We find that such configurations are possible even for flat black hole horizon, unlike the AdS black hole case. We construct the brane world model with an orbifold structure S^1/Z_2 in such bulk background. We also study massless bulk scalar field.
