  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 greybody 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 spacetime are discussed. We
finally study the emission of Hawking radiation in the bulk: greybody 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.
