Fermion evaporation of a black hole off a tense brane

TL;DR

This paper investigates the emission spectrum of massless fermions from six-dimensional black holes off a tense brane, using the WKBJ approximation to analyze how the tension affects evaporation.

Contribution

It provides numerical plots of the power spectrum and multiplicity factors for eigenvalues, extending understanding of black hole evaporation in higher dimensions with brane tension.

Findings

Emission spectrum depends on brane tension

Multiplicity factors reduce to standard case when tension vanishes

Numerical analysis of fermion emission in six dimensions

Abstract

Using the WKBJ approximation we obtain numerical plots of the power emission spectrum for the evaporation of massless bulk Dirac fermions from six dimensional black holes off a tense 3-brane with codimension two. We also present the multiplicity factors for eigenvalues of the deficit four sphere and show that these reduce to the usual case in the tenseless limit.
