Black holes radiate mainly on the brane

We examine the evaporation of a small black hole on a brane in a world with large extra dimensions. Since the masses of many Kaluza-Klein modes are mu ch smaller than the Hawking temperature of the black hole, it has been clai med that most of the energy is radiated into these modes. We show that this is incorrect. Most of the energy goes into the modes on the brane. This ra ises the possibility of observing Hawking radiation in future high energy c olliders if there are large extra dimensions.
