We start by reviewing the existing literature on the creation of black holes during high-energy particle collisions, both in the absence and in the presence of extra, compact, spacelike dimensions. Then, we discuss in detail the properties of the produced higher-dimensional black holes, namely the horizon radius, temperature and life-time, as well as the physics that governs the evaporation of these objects, through the emission of Hawking radiation. We first study the emission of visible Hawking radiation on the brane: we derive a master equation for the propagation of fields with arbitrary spin in the induced-on-the-brane black hole background, and we review all existing results in the literature for the emission of scalars, fermions and gauge bosons during the spin-down and Schwarzschild phases of the life of the black hole. Both analytical and numerical results for the graybody factors and radiation spectra are reviewed and exact results for the number and type of fields emitted on the brane as a function of the dimensionality of space–time are discussed. We finally study the emission of Hawking radiation in the bulk: graybody factors and radiation spectra are presented for the emission of scalar modes, and the ratio of the missing energy over the visible one is calculated for different values of the number of extra dimensions.

Black Holes in Higher Dimensions (2008, background): “As mentioned in Section 2, this is outside the scope of this paper and we refer to [30, 155] for reviews.”
Instability of the massive Klein-Gordon field on the Kerr spacetime (2007, background): “With n ≥ 1 additional dimensions, possibilities include black strings (with event horizon topology S × R) and black p-branes (S × R), as well as black holes (R) [28].”
Black holes as bubble nucleation sites (2013, background): “Another interesting generalization of our study would be to explore the effect in extra dimensional scenarios, such as [35, 36], where the Planck mass can drop substantially, leading to interesting new black hole phenomenology, (for a review see [37]).”
