Abstract: We analyse a family of brane-world black holes which solve the effectivefour-dimensional Einstein equations for a wide range of parameters related tothe unknown bulk-brane physics. We first constrain the parameters using knownexperimental bounds and, for the allowed cases, perform a numerical analysis oftheir time evolution, which includes accretion through the Earth. The study isaimed at predicting the typical behavior one can expect if such black holeswere produced at the LHC. Most notably, we find that, under no circumstances,would the black holes reach the hazardous regime of Bondi accretion.Nonetheless, the possibility remains that black holes live long enough toescape from the accelerator and even from the Earth-s gravitational field andresult in missing energy from the detectors.
