Computes exact bulk and brane greybody (transmission) factors for Hawking emission from a higher-dimensional Schwarzschild black hole of the type relevant to LHC extra-dimension scenarios, refining the crude geometric-cross-section evaporation estimates of Dimopoulos-Landsberg/Giddings-Thomas into quantitative emission spectra across the full evaporation history. arXiv:hep-ph/0309054. relevance_note: strengthens the quantitative evaporation-rate case specifically for the higher-dimensional black holes the LHC would actually produce (as opposed to generic 4D Hawking calculations).
