Footprints of Higher-Dimensional Decaying Black Holes

TL;DR

This paper reviews the emission characteristics of higher-dimensional black holes, focusing on Hawking radiation during different phases, angular variation, graviton spectra, and energy distribution between bulk and brane.

Contribution

It provides a comprehensive overview of the current understanding of Hawking radiation from higher-dimensional black holes, including new insights into angular emission patterns and bulk-to-brane energy transfer.

Findings

Angular variation affects radiation emission on the brane.

Graviton spectra in the bulk are characterized.

Particle mass influences bulk-to-brane energy distribution.

Abstract

We review the current results for the emission of Hawking radiation by a higher-dimensional black hole during the Schwarzschild and the spin-down phases. We discuss particularly the role of the angular variation of the emitted radiation on the brane during the latter phase, the radiation spectra for gravitons in the bulk, and the effect of the mass of the emitted particles in determining the bulk-to-brane energy balance.
