We consider the production and decay of mini black holes in brane world scenarios. After discussing evaluation of the production cross section of higher dimensional rotating black holes and black rings, the master equation for general spin-s fields confined on brane world is derived. The master equation is separable for any spin-s in any dimension D = 4 + n. For five-dimensional black holes, we obtain analytic expressions for the greybody factors in low frequency expansion.
