“…However, it turns out that the next-to-leading order terms in the expansion of the lowest partial-wave, denoted by ellipses in Eq. (88), are of the same order as the leading terms of the higher partial waves, and thus should also be taken into account. When this is done, we are finally led to a decrease of the greybody factor for scalar fields with n. An extreme caution is therefore necessary when one deals with simplified expressions as the Eqs.…”

We start by reviewing the existing literature on the creation of black holes during highenergy 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 higherdimensional 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-thebrane 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.

“…The subscript in (M 2 ) refers to the fact that this is evolution scenario number two. Equation (12) suggests that for (d > 1) the growth rate due to thermal motion inside of the earth would be too slow to do any harm within the lifetime of the earth. However, for low black hole velocities (as they would be possible at LHC) equation (12) has to be corrected by taking additional effects such as Bondi accretion into account.…”

The upcoming high energy experiments at the LHC are one of the most outstanding efforts for a better understanding of nature. It is associated with great hopes in the physics community. But there is also some fear in the public, that the conjectured production of mini black holes might lead to a dangerous chain reaction. In this paper we summarize the most straight forward arguments that are necessary to rule out such doomsday scenarios.Comment: 17 pages, 2 figure

“…However, the total cross section obtained by summing the rotating and non-rotating cross sections is about 2 to 3 times higher than the non-rotating case. Kotwal and Hays [15] have analyzed the angular momentum distribution of black holes by computing the production probability using the partial wave expansion of the initial state. They assumed a step-function interaction Hamiltonian with an arbitrary normalization.…”

Black hole production at the Large Hadron Collider (LHC) was first discussed in 1999. Since then, much work has been performed in predicting the black hole cross section. In light of the start up of the LHC, it is now timely to review the state of these calculations. We review the uncertainties in estimating the black hole cross section in higher dimensions. One would like to make this estimate as precise as possible since the predicted values, or lower limits, obtain for the fundamental Planck scale and number of extra dimensions from experiments will depend directly on the accuracy of the cross section. Based on the current knowledge of the cross section, we give a range of lower limits on the fundamental Planck scale that could be obtained at LHC energies.
