Distributions of charged massive scalars and fermions from evaporating higher-dimensional black holes

Understand

A detailed numerical analysis is performed to obtain the Hawking spectrum for charged, massive brane scalars and fermions on the approximate background of a brane charged rotating higher-dimensional black hole constructed in arXiv:0907.5107.

• We formulate the problem in terms of a "spinor-like" first order system of differential wave equations not only for fermions, but for scalars as well and integrate it numerically.
• Flux spectra are presented for non-zero mass, charge and rotation, confirming and extending previous results based on analytic approximations.
• In particular we describe an inverted charge splitting at low energies, which is not present in four or five dimensions and increases with the number of extra dimensions.
