Probing extra dimensions with higher dimensional black hole analogues?

TL;DR

This paper explores the possibility of detecting extra dimensions through higher dimensional black hole analogues by extending acoustic black hole models and calculating Hawking radiation absorption cross-sections.

Contribution

It introduces a generalized higher dimensional black hole analogue model and computes Hawking radiation absorption in both brane and bulk scenarios.

Findings

Absorption cross-sections are calculated for higher dimensional black holes.

The model extends acoustic black hole metrics to arbitrary dimensions.

Results suggest potential observational signatures of extra dimensions.

Abstract

We propose that extra dimensions might be detected with higher dimensional analogues of black holes. The usual 4-dimensional acoustic(sonic)black hole metric is extended to arbitrary dimensions. The absorption cross-section of Hawking radiation on the brane and in the bulk are calculated in the semiclassical approximation.
