Particle emission from a black hole on a tense codimension-2 brane

TL;DR

This paper analytically calculates the grey-body factors for black holes on a tense codimension-2 brane, revealing particle emission characteristics in both low and high frequency regimes, with implications for extra-dimensional theories.

Contribution

It provides explicit analytical expressions for particle emission from black holes on a tense brane, including effects of brane tension and extra dimensions, extending previous models.

Findings

Explicit grey-body factors for particles emitted on and off the brane.

Analytical expressions valid in low and high frequency regimes.

Results applicable to arbitrary extra dimensions when brane tension is zero.

Abstract

We calculate analytically grey-body factors of Schwarzschild black-holes localized on a 3-brane of finite tension and codimension 2. We obtain explicit expressions for various types of particles emitted in the bulk as well as on the brane in both the low and high frequency regimes. In the latter case, we obtain expressions which are valid for arbitrary number of extra dimensions if the brane tension vanishes.
