Calculable Corrections to Brane Black Hole Decay II: Greybody Factors for Spin 1\/2 and 1

The production of black holes in extra-dimensional brane-world theories can lead to detectable signals via the Hawking evaporation of the black hole to brane-localized Standard Model modes. We calculate, as a function of partial wave number and number of toroidally compactified extra dimensions, the...

Sumario:The production of black holes in extra-dimensional brane-world theories can lead to detectable signals via the Hawking evaporation of the black hole to brane-localized Standard Model modes. We calculate, as a function of partial wave number and number of toroidally compactified extra dimensions, the leading correction to the energy spectrum of such Hawking radiation (the greybody factors) for decay into spin 1/2 fermions and spin 1 gauge fields localised on the Standard Model brane. The greybody factors for both types of fields are enhanced as the number of extra dimensions increases.
